As Auckland and Northland brace for more atrocious weather, city leaders are calling for funding to repair the city's broken infrastructure to be along the lines of the help given to Christchurch after the quakes. Auckland deputy mayor Desley Simpson says that the damage so far is equivalent to the biggest non earthquake event the country has ever had and should be treated accordingly. The Opportunities Party says the "alliance" model established after the earthquakes, was effective and would work for Auckland's rebuild, because it provides a structure that the Central Government can fund directly. ToP leader Raf Manji was a Christchurch councillor after the quakes and closely involved in the rebuild. He tells Kathryn Ryan it is vital to ensure water and transport infrastructure is repaired quickly and efficiently, especially with a view to future extreme weather events - and there is much to learn from the post-quake rebuild.
Rick Wentz is a Chartered geotechnical engineer originally from Northern California who has lived in New Zealand since 2011 - coming here in response to the Christchurch earthquakes. Rick talks to Mark about seismic risk - what it means for the general community and the role of a geotechnical engineering in helping to manage it.
Earlier this morning Christchurch's Cathedral Square saw its first dawn service since the earthquake in 2011. The city's Mayor Phil Mauger was there.
A huge milestone in the rebuild of the Christchurch Cathedral.
Twelves years since the Canterbury earthquakes caused extensive damage to the building, community leaders and project managers have gathered inside the cathedral this morning for the first time since the quakes.
It also marks the completion of stablisation phase of the project.

Sir Miles Warren and Maurice Mahoney were architectural revolutionaries who built a legendary partnership spanning 37 years. A new film currently in production aims to celebrate their incredible legacy and document the bitter fight to save their most iconic building - the Christchurch Town Hall - from demolition after the 2011 earthquake. Co-director and Maurice's daughter Jane Mahoney talks to Mark Leisham about the pairs legacy and the process of making the film.
More than 11,000 people reported feeling the earthquake that hit just after 2am on Friday.
The magnitude 4.8 quake was centred 5-kilometres south of Te Aroha, at a depth of 6-kilometres.
People from Kaitaia, through to the sodden regions of Auckland, Bay of Plenty, Coromandel, and even down in Christchurch, reported feeling it.
A series of weaker aftershocks began to strike 40 minutes later, although there are no immediate reports of damage as of yet.
It's not the first quake to hit Te Aroha this year - a 5.1 quake rattled the town on January 4.
Te Kuiti resident Zane Burdett and Kees Meinderts from Motumaoho, just south of Morrinsville, spoke to Corin Dann.
What does leadership look like in a disaster? David compares Auckland Mayor Wayne Brown's leadership this week with how Bob Parker and Lianne Dalziel coped with the Christchurch earthquakes and terror attacks. He looks at how current Christchurch mayor Phil Mauger's council is faring and whether reality meets the rhetoric and what's happened to the city's Metro Sports facility, one of the anchor projects in the rebuild.
Now have you ever wished you could play some cricket in the house on a rainy day? Well for one Christchurch family that dream's become a reality. Glenn Bongartz, with the help of his architect, upgraded his earthquake rebuild to feature a cricket wicket in the attic of the house. Glenn told Jimmy Ellingham how they did it.
The families of the victims of the CTV building collapse in Christchurch have told an engineering disciplinary hearing they've been waiting 12 years for accountability.
The building collapsed in the February 2011 earthquake killing 115 people.
It was designed by Dr Alan Reay's firm - Reay was criticised by the Earthquake Royal Commission for handing sole responsibility of it to an inexperienced employee.
Reay has tried to stop the disciplinary process going ahead but it got underway in Christchurch today.
Reporter Anna Sargent spoke to Charlotte Cook.
The historic Townsend Teece telescope in Otautahi Christchurch was badly damaged in the 2011 earthquake, but has been expertly restored and is now reinstalled back in its central city home at the Arts Centre.
Protecting live music venues is taking on a new urgency in Christchurch, with the popular 12 Bar announcing it will close at the end of the month. With people flocking back to live in the central city after the earthquakes, there have been more complaints about noise from entertainment venues. But the local music scene says positive changes are in the works, so residents and live venues can live in harmony. Niva Chittock reports.
The Anzac Day Dawn service returns to Christchurch's Cathedral Square tomorrow, the first time since the 2011 earthquake.

A complaint against an engineer whose firm designed the CTV building that collapsed in the Christchurch earthquake will be heard by a disciplinary committee on Monday.
One-hundred-and-fifteen people were killed when the six-storey building came down in February 2011.
Dr Alan Reay lost a High Court bid to stop the hearing.
Reporter Anna Sargent spoke to Corin Dann.
The government's looking overseas to get more hands on deck to help with the rebuild from Cyclone Gabrielle.
A new short-term Recovery Visa will bring in specialist foreign workers through a similar pathway used after the Christchurch and Kaikoura earthquakes.
The visas will be fast-tracked with officials aiming to get applications through within seven days.
Corn Dann spoke with immigration minister Michael Wood.
The government is crowdsourcing the cyclone recovery bill. It has launched an international fundraising effort, modelled on the Christchurch Earthquake Appeal - which raised almost $100 million.
A separate special Lotto draw will also be held on March 18 with all proceeds going to affected communities.
Prime Minister Chris Hipkins has urged New Zealanders to get behind the effort.
He defended asking people to chip in when the cost-of-living is so high.
A panel with Michael Bell, Steph Walker and Kiri Jarden. It’s almost 13 years since the devastating earthquake of 22 February 2011, which forced 70 percent of the Ōtautahi Christchurch CBD to be demolished.
While the rebuild has been a slow and often difficult process in visions meeting reality, there is also much to celebrate in the city taking up the opportunity, through art and design, to remake it as a place for all.
Twelve years after the CTV building collapsed during the Christchurch earthquake, families of the victims killed inside have told an engineering disciplinary hearing they want justice and accountability. 115 people died when the six-storey building came down in February 2011. A complaint against an engineer whose firm designed the building is being heard by an Engineering New Zealand disciplinary committee. Dr Alan Reay lost a High Court bid to stop the hearing.

His surgeon father decides to try to send him and mother away from the violence - and Amir finds himself on a perilous journey - one that puts him on the other side of the planet. His path crosses with Milly, an angry teenager still reeling from the loss of her mother in the Christchurch earthquakes. Blair McMillan runs a swim school with his wife Karen by day - and Here Upon the Tide is his debut novel. He joins Susie to talk about it.
The Anglican church is considering whether to sell Christchurch's cardboard cathedral to plug a shortfall in the budget for restoring the original descimated in the earthquakes. The church leadership will discuss the future of the cardboard building during meetings at the weekend. It opened opposite Latimer square in 2013 as a temporary place of worship, but soom became popular with tourists too. Meanwhile a 2017 estimate put the cost of restoring the actual Cathedral at just over $100 million, but that's since ballooned to north of $155 million. Harcourts real estate agent, Mark O'Loughlin, speaks to Lisa Owen from Christchurch. [embed] https://players.brightcove.net/6093072280001/default_default/index.html?videoId=6336786667112
It is well established that urban green areas provide a wide range of social, aesthetic, environmental and economic benefits. The importance of urban green spaces has been known for decades; however the relationship between urban livability and green areas, as incorporated in overall urban green structure, has become the focus of international studies during the last 10 to 15 years. The spatial structure of green space systems has important consequences for urban form; configuring urban resources, controlling urban size, improving ecological quality of urban areas and preventing or mitigating natural disasters. However, in the field of architecture or urban design, very little work has been done to investigate the potential for built form to define and differentiate the edge to a green corridor ... This thesis therefore poses the hypothesis that architecture and urban design critically mediate between city and green corridor, through intensification and definition of the built edge, as a means of contributing to an ecological city form.
After being trapped for hours on the 22nd floor of a hotel following the 2011 Christchurch earthquake, Andy Cleverley decided life had to change. Chucking in his corporate life, he bought an old school bus, converted it into an off-grid motorhome and set off travelling the country with his young family. Documenting everything along the way he created Bus Life NZ - followed by over 46,000 people and viewed by millions. Now he's done it all again with a second bus and a second YouTube season.
There's good news of sorts on the building-inspection front in Auckland.
After nearly seven days of fanning out across the city inspecting damaged buildings - the biggest such deployment of building inspectors since the Christchurch earthquake emergency - the operation will be scaled back this weekend.
There are currently around 95 inspectors in the field who have checked 3,500 buildings. As of 6pm last night 190 buildings were red stickered, and a further 790 yellow stickered.
The most red stickered areas are Mount Albert/Mt Eden with 54 and the North Shore with 32.
Auckland Council general manager building consents Ian McCormick spoke to Corin Dann.
The susceptibility of precast hollow-core floors to sustain critical damage during an earthquake is now well-recognized throughout the structural engineering community in New Zealand. The lack of shear reinforcement in these floor units is one of the primary reasons causing issues with the seismic performance of these floors. Recent research has revealed that the unreinforced webs of these floor units can crack at drift demands as low as 0.6%. Such observation indicates that potentially many of the existing building stock incorporating hollow-core flooring systems in cities of relatively high seismic activity (e.g. Wellington and Christchurch) that probably have already experienced a level of shaking higher than 0.6% drift in previous earthquakes might already have their floor units cracked. However, there is little information available to reliably quantify the residual gravity load-carrying capacity of cracked hollow-core floor units, highlighting the need to understand the post-cracking behavior of hollow-core floor units to better quantify the extent of the risk that cracked hollow-core floor units pose.
The Mѡ=7.1 Darfield (Canterbury) earthquake struck on 4 September 2010, approximately 45 km west of Christchurch, New Zealand. It revealed a previously unknown fault (the Greendale fault) and caused billions of dollars of damage due to high peak ground velocities and extensive liquefaction. It also triggered the Mw=6.3 Christchurch earthquake on 22 February 2011, which caused further damage and the loss of 185 lives. The objective of this research was to determine the relationship between stress and seismic properties in a seismically active region using manually-picked P and S wave arrival times from the aftershock sequence between 8 September 2010-13 January 2011 to estimate shear-wave splitting (SWS) parameters, VP =VS-ratios, anisotropy (delay-time tomography), focal mechanisms, and tectonic stress on the Canterbury plains. The maximum horizontal stress direction was highly consistent in the plains, with an average value of SHmax=116 18 . However, the estimates showed variation in SHmax near the fault, with one estimate rotating by as much as 30° counter-clockwise. This suggests heterogeneity of stress at the fault, though the cause remains unclear. Orientations of the principal stresses predominantly indicate a strike-slip regime, but there are possible thrust regimes to the west and north/east of the fault. The SWS fast directions (ø) on the plains show alignment with SHmax at the majority of stations, indicating stress controlled anisotropy. However, structural effects appear more dominant in the neighbouring regions of the Southern Alps and Banks Peninsula.

The seismic performance of soil profiles with potentially liquefiable deposits is a complex phenomenon that requires a thorough understanding of the soil properties and ground motion characteristics. The limitations of simplified liquefaction assessment methods have prompted an increase in the use of non-linear dynamic analysis methods. Focusing on onedimensional site response of a soil column, this thesis validated a soil constitutive model using in-situ pore pressure measurements and then assessed the influence of input ground motion characteristics on soil column response using traditional and newly developed metrics. Pore pressure recordings during the Canterbury Earthquake Sequence (CES) in New Zealand were used to validate the PM4Sand constitutive model. Soil profile characterization was key to accurate prediction of excess pore pressure response and accounting for any densification during the CES. Response during multiple earthquakes was captured effectively and cross-layer interaction demonstrated the model capability to capture soil response at the system-level. Synthetic and observed ground motions from the Christchurch earthquake were applied to the validated soil column to quantify the performance of synthetic motions. New metrics were developed to facilitate a robust comparison to assess performance. The synthetic input motions demonstrated a slightly larger acceleration and excess pore pressure response compared to the observed input motions. The results suggest that the synthetic motions may accumulate higher excess pore pressure at a faster rate and with fewer number of cycles in the shear response. This research compares validated soil profile subject to spectrally-matched pulse and non-pulse motions, emphasizing the inclusion of pulse motions with distinctive characteristics in ground motion suites for non-linear dynamic analysis. However, spectral matching may lead to undesired alterations in pulse characteristics. Cumulative absolute velocity and significant duration significantly differed between these two groups compared to the other key characteristics and contributed considerably to the liquefaction response. Unlike the non-pulse motions, not all of the pulse motions triggered liquefaction, likely due to their shorter significant duration. Non-pulse motions developed a greater spatial extent of liquefaction triggering in the soil profile and extended to a greater depth.
Aotearoa has undoubtedly some of the most beautiful landscapes in the world, a privilege for its inhabitants. However, as our cities have developed post-colonisation, the connection between the natural environment and its occupants has diminished. Designers play a vital role within an ever evolving world to progress the built environment in a way that reflects and restores vital values that have been deprioritised. Future practice should prioritise diversity, care for the land, enhancement of community space, and sustainable practices.
This research sets out to demonstrate that new design methodologies can encourage kaitiakitanga, whilst meeting the needs of urban public space. Initially through critical analysis and literature based research, a study of Ōtautahi Christchurch, the South Island’s largest city, was undertaken. The principles of a ‘15 minute city’ were also explored and applied to the city, establishing issues within the built environment that drove the overall research direction.
Through the tools of critical reflection and a research through design methodology, a design toolkit was constructed. This toolkit sets out to provide designers with a simple streamlined method of developing urban interventions that are sustainable and beneficial for human well-being. The toolkit incorporates an abstraction of the ‘15 minute city’ ideology and introduces the concepts of evolving green transportation routes within cities. Ōtautahi Christchurch, a city with a significant history of earthquake-caused damage, was chosen as the primary site for the application of this research’s proposed toolkit. The city becomes a canvas for an urban rebuild that explores and aims to set a precedent for a progressive 21st-century city.
A key finding as the toolkit research developed was the idea of a ‘temporary’ phase or intervention, being added to traditional design methodologies prior to permanent building. The research explains how this temporary phase could more actively engage diverse user groups and create active conversations between communities and designers.
The refined toolkit sets outs proposed timeline phases, methods of site analysis and development of design drivers. Alongside this, a modular architectural system establishes a design proposal for the temporary phase of an individual site within an evolving green route. This outcome provides further opportunity for realistic testing, which would actively involve communities and aims to shift our priorities within urban development. The introduction of the ‘temporary’ phase is beneficial in mitigating psychological implications on people and limiting physical impacts on the landscape.
The final design stage of the thesis applied the toolkit process to three sites in Ōtautahi Christchurch. Through a holistic lens, the toolkit framework set out methods to collate information that provides guidance for development on the sites. While some layers are initiated simply by recognising site characteristics, others are informed through software such as GIS.
Connected by a proposed green transport route, the three initial sites are developed with temporary interventions that utilise the modular design set out previously in the research. Contextualising the interventions on real world sites tested the flexibility of the system and allowed for critical reflection on the applicability of the toolkit to Aotearoa.
The research concludes by identifying future research opportunities and speculates on possible applications of its findings within the real world. Temporary Permanence highlights the significant role that we, as designers, have in shifting urban priorities to create more holistic, sustainable, and inclusive cities for people and the planet.
