A video of an interview with Prime Minister John Key about several topical issues. One of these issues is the housing crisis in Christchurch. Key talks about fast tracking the release of land in Christchurch, making sure there are enough resources in the city for building, and working with the Christchurch City Council around consenting. He also talks about the possibility of the National Party winning the Christchurch East by-election.

A signpost pointing 'West' and 'East'. The sign pointing West is intact; that indicating East is broken and barely hanging on to the post. Refers to the condition of Christchurch City after the earthquakes of 2010 and 2011; the western wealthier suburbs were less damaged than the poorer Eastern suburbs. Also, progress on repair and rehabilitation of eastern housing had been slow. The redesign of the city centre seemed to be a western suburb priority which ignored the poverty and misery of living conditions on the east. Quantity: 1 digital cartoon(s).

One of many disabled carparks outside what used to be one of the great sporting complexes in New Zealand. The Queen Elizabeth II Park complex in north-east Christchurch was built initially for the 1974 Commonwealth Games and was used for track and field and the adjoining pool complex had swimming and diving. It was built on an area that was used...

Lincoln University was commissioned by the Avon-Otakaro Network (AvON) to estimate the value of the benefits of a ‘recreation reserve’ or ‘river park’ in the Avon River Residential Red Zone (ARRRZ). This research has demonstrated significant public desire and support for the development of a recreation reserve in the Avon River Residential Red Zone. Support is strongest for a unique natural environment with native fauna and flora, healthy wetlands and rivers, and recreational opportunities that align with this vision, such as walking, cycling and water-based sporting and leisure activities. The research also showed support for a reserve that promotes and enables community interaction and wellbeing, and is evident in respondents’ desires for community gardens, regular festivals and markets, and the physical linking of the CBD with eastern suburbs through a green corridor. There is less support for children’s playgrounds, sports fields or open grassed areas, all of which could be considered as more typical of an urban park development. Benefits (willing to pay) to Christchurch residents (excluding tourists) of a recreation reserve could be as high as $35 million each year. Savings to public health costs could be as high as $50.3 million each year. The incorporation or restoration of various ecosystems services, including water quality improvements, flood mitigation and storm water management could yield a further $8.8 million ($19, 600) per hectare/year at 450 ha). Combined annual benefits of a recreational reserve in the ARRRZ are approximately $94.1 million per annum but this figure does not include potentially significant benefits from, for example, tourism, property equity gains in areas adjacent to the reserve, or the effects of economic rejuvenation in the East. Although we were not able to provide costing estimates for park attributes, this study does make available the value of benefits, which can be used as a guide to the scope of expenditure on development of each park attribute.

A video of Rachel Young describing the changes that will be made to streets in the Christchurch central city, under the Accessible Transport Plan. The video includes time-lapse footage of a car driving down Durham Street, Tuam Street, Kilmore Street, Salisbury Street, and Rolleston Avenue. Young explains that Tuam Street will become a west-to-east one-way street, that a new bus exchange will be built on the block bordered by Tuam, Colombo, Manchester, and Lichfield Streets, that a super stop will be added at the hospital and on Manchester Street, and that Kilmore and Salisbury Streets will be turned into two-way streets. She also explains that the speed limit will be dropped to 30 km/h in the area bordered by Rolleston Avenue, St Asaph Street, Madras Street, and Kilmore Street.

Topics - Official statistics released today show New Zealand's population has increased by 214,000 people in the seven years since the last census. The census, usually held every five years, was delayed in 2011 due to the Christchurch earthquakes. In what has been described as a "stealthy assault" in Somalia - and also in a raid in Libya's capital - US special forces have struck out against Islamic extremists who carried out terrorist attacks in East Africa. The commandos snatched a Libyan al-Qaida leader allegedly involved in the bombings of US embassies 15 years ago - but aborted a mission to capture a terrorist suspect linked to last month's Nairobi shopping mall attack after a fierce firefight.

This paper provides a summary of the ground motions observed in the recent Canterbury, New Zealand earthquake sequence. The sequence occurred in a region of relatively moderate seismicity, 130km to the east of the Alpine Fault, the major plate-boundary in the region. From an engineering perspective, the sequence has been primarily comprised of the initial 04/09/2010 Darfield earthquake (Mw7.1) followed by the 22/02/2011 Christchurch earthquake (Mw6.3), and two aftershocks on 13/06/ 2011 (Mw5.3 and 6.0, respectively). The dense spacing of strong motions in the region, and their close proximity to the respective causative faults, has resulted in strong ground motions far exceeding the previous catalogue of strong motion observed in New Zealand. The observed ground motions have exhibited clear evidence of: (i) near-source directivity; (ii) sedimentary basin focusing, amplification and basin effect refraction; (iii) non-linear site response; (iv) cyclic mobility postliquefaction; and (v) extreme vertical ground motions exceeding 2g, among others.

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.
