Aerial footage of a site in Avondale where several liquefaction remediation options are being tested. Gelignite explosives have been buried throughout the site. These will be set off to simulate liquefaction caused by an earthquake. The result, if successful, will help EQC protect people's houses from future earthquakes, and settle land claims. The video was recorded using a drone aircraft.

A digitally manipulated image of liquefaction around a house in Avondale. The photographer comments, "The bottom of the gates were swallowed up by liquefaction, but the house still looked in good condition, which was confirmed by builders just going in to work on the property. It is in the Christchurch red zone, which after testing has been deemed unsuitable for houses to be built on. All the land will be bought by the Government and they would also buy any properties that could be repaired. The remaining insured property owners will get a payment from the insurance company. All the buildings are condemned to be knocked down".

A residential street in New Brighton. Liquefaction still lines the street, and lampposts are leaning in different directions. The photographer comments, "This is the New Brighton red zone, which is parallel to the Avon River. The area suffered serious liquefaction during the numerous earthquakes/aftershocks and the land is being bought by the government. Although the houses do not look too bad in the background they have suffered badly. On the day I took this picture the council had just hours before cut the grass, which made the area look less abandoned".

A digitally manipulated image of two chairs sitting among rubble. The photographer comments, "There is a strip of land that has been declared as the red zone. This means that the houses facing towards the tidal estuary must be abandoned as they are on land that has been declared uneconomic to repair after the Christchurch earthquakes. These chairs are at the front of one of these properties that will be bulldozed. These seem to be saying come hell or high water we will not be moved".

A sign on a fence in Bexley reads "17 19 21. We are all home, smiling, staying positive, looking forward, A.J. included." The photographer comments, "These three neighbour families in the Bexley Christchurch red zone are all great friends. They are so fond of each other that they want to buy a big parcel of land and then build three homes next to each other".

8 Velsheda Street, Bexley, Christchurch, across the road from my house was demolished a week or so ago, just one of many demolitions of Red Zone properties at the moment. This house was about ten years old and suffered land damage during the 4th September 2010 and 22nd February 2011 earthquakes. The same fate awaits my house later in the year o...

Balloons and a sign advertising a garage sale hang from a fence. The photographer comments, "Today, 23/7/2011 the Bexley community in Christchurch got together and held a Bexley wide garage sale. You could pick up a map of the garage sales in Arncliffe St, which meant that people could find all the garage sales even if they were on the back sections. People got together with close neighbours to hold joint Garage Sales. In the area where the garage sales were held all the homes have been 'written off' by the government, as the land on which they sit is too damaged by the Christchurch earthquakes to repair. In places it looked more like a ships graveyard with the hulls of the houses sinking lopsidedly into the sand. Unfortunately for nearly everyone in the red zone they cannot rebuild a new home as sections to build on start now around $2,000 and the government is not paying them enough to buy a plot of land and build a new home. The choices for Bexley residents in most cases is to rent, buy a house at least a few years old or move to Australia to start again. I was told that up to 80% could be off to Oz".

A chimpanzee paints with a palette of colours. Context: After the earthquakes in Christchurch buildings and areas were designated green, blue, red or white depending on the degree of damage. Buildings in the 'red' zone were then examined to ascertain whether they should be demolished or restored and sometimes the land itself was deemed unsafe. There have been many controversial decisions made which is the point the cartoon makes. Quantity: 1 digital cartoon(s).

The 2010 and 2011 earthquakes in the region of Canterbury, New Zealand caused widespread damage and the deaths of 185 people. Suburbs on the eastern side of Christchurch and in the satellite town of Kaiapoi, 20 kilometres north of Christchurch, were badly damaged by liquefaction. The Canterbury Earthquake Recovery Authority (CERA), a government organisation set up in the wake of the earthquakes, began to systematically zone all residential land in 2011. Based on the possibility for land remediation, 7860 houses in Christchurch and Kaiapoi were zoned red. Those who were in this zone were compensated and had to buy or build elsewhere. The other zone examined within this research – that of TC3 – lies within the green zone. Residents, in this zone, were able to stay in their houses but land was moderately damaged and required site-specific geotechnical investigations. This research sought to understand how residents’ senses of home were impacted by a disaster and the response efforts. Focusing on the TC3 and red zone of the eastern suburbs and the satellite town of Kaiapoi, this study interviewed 29 residents within these zones. The concept of home was explored with the respondents at three scales: home as a household; home as a community; and home as a city. There was a large amount of resistance to the zoning process and the handling of claims by insurance companies and the Earthquake Commission (EQC) after the earthquakes. Lack of transparency and communication, as well as extremely slow timelines were all documented as failings of these agencies. This research seeks to understand how participant’s sense of home changed on an individual level and how it was impacted by outside agencies. Homemaking techniques were also focused on showing that a changed sense of home will impact on how a person interacts with a space.

During 2010 and 2011, a series of major earthquakes caused widespread damage in the city of Christchurch, New Zealand. The magnitude 6.3 quake in February 2011 caused 185 fatalities. In the ensuing months, the government progressively zoned residential land in Christchurch on the basis of its suitability for future occupation (considering damage from these quakes and future earthquake risk). Over 6,000 homes were placed in the ‘red-zone’, meaning that property owners were forced to sell their land to the Crown. This study analysed patterns of residential mobility amongst thirty-one red-zone households from the suburb of Southshore, Christchurch. Drawing on interviews and surveys, the research traced their experience from the zoning announcement until they had moved to a new residence. The research distinguished between short (before the zoning announcement) and long term (post the red zone ‘deadline’) forms of household relocation. The majority of households in the study were highly resistant to short term movement. Amongst those which did relocate before the zoning decision, the desire to maintain a valued social connection with a person outside of the earthquake environment was often an important factor. Some households also moved out of perceived necessity (e.g. due to lack of power or water). In terms of long-term relocation, concepts of affordability and safety were much more highly valued by the sample when purchasing post-quake property. This resulted in a distinct patterning of post-quake housing location choices. Perceived control over the moving process, relationship with government organisations and insurance companies, and time spent in the red-zone before moving all heavily influenced participants’ disaster experience. Contrary to previous studies, households in this study recorded higher levels of subjective well-being after relocating. The study proposed a typology of movers in the Christchurch post-disaster environment. Four mobility behaviours, or types, are identified: the Committed Stayers (CSs), the Environment Re-Creators (ERCs), the Resigned Acceptors (RAs), and the Opportunistic Movers (OMs). The CSs were defined by their immobility rather than their relocation aspirations, whilst the ERCs attempted to recreate or retain aspects of Southshore through their mobility. The RAs expressed a form of apathy towards the post-quake environment, whereas, on the other hand, the OMs moved relative to pre-earthquake plans, or opportunities that arose from the earthquake itself. Possibilities for further research include examining household adaptability to new residential environments and tracking further mobility patterns in the years following relocation from the red- zone.

Shows a shamrock superimposed on the city of Christchurch. It represents the green zone. Context: Probably refers to the zoning review process for those insured residential property owners who wish to query their land zoning. Zoning of flat land in greater Christchurch began in June last year and was completed last month. Over that period 7253 properties were zoned red as unsuitable for residential occupation due to significant earthquake damage; while a further 180,000 properties were zoned green as suitable for residential occupation, some with conditions.

The recent earthquakes in Canterbury have left thousands of Christchurch residents’ homeless or facing the possibility of homelessness. The New Zealand Government, so far, have announced that 5,100 homes in Christchurch will have to be abandoned as a result of earthquake damaged land (Christchurch City Council, 2011). They have been zoned red on the Canterbury Earthquake Recovery Authority (CERA) map and there are another 10,000 that have been zoned orange, awaiting a decision (Christchurch City Council, 2011). This situation has placed pressures on land developers and local authorities to speed up the process associated with the development of proposed subdivisions in Christchurch to accommodate residents in this situation (Tarrant, 2011).

At the conclusion of the 2010 and 2011 Canterbury earthquakes more than 5100 homes had been deemed unsafe for habitation. The land and buildings of these were labelled “red zoned” and are too badly damaged for remediation. These homes have been demolished or are destined for demolition. To assist the red zone population to relocate, central government have offered to ‘buy out’ home owners at the Governmental Value (GV) that was last reviewed in 2007. While generous in the economic context at the time, the area affected was the lowest value land and housing in Christchurch and so there is a capital shortfall between the 2007 property value and the cost of relocating to more expensive properties. This shortfall is made worse by increasing present day values since the earthquakes. Red zone residents have had to relocate to the far North and Western extremities of Christchurch, and some chose to move even further to neighbouring towns or cities. The eastern areas and commercial centres close to the red zone are affected as well. They have lost critical mass which has negatively impacted businesses in the catchments of the Red Zone. This thesis aims to repopulate the suburbs most affected by the abandonment of the red zone houses.  Because of the relative scarcity of sound building sites in the East and to introduce affordability to these houses, an alternative method of development is required than the existing low density suburban model. Smart medium density design will be tested as an affordable and appropriate means of living. Existing knowledge in this field will be reviewed, an analysis of what East Christchurch’s key characteristics are will occur, and an examination of built works and site investigations will also be conducted.  The research finds that at housing densities of 40 units per hectare, the spatial, vehicle, aesthetic needs of East Christchurch can be accommodated. Centralising development is also found to offer better lifestyle choices than the isolated suburbs at the edges of Christchurch, to be more efficient using existing infrastructure, and to place less reliance on cars. Stronger communities are formed from the outset and for a full range of demographics.  Eastern affordable housing options are realised and Christchurch’s ever expanding suburban tendencies are addressed. East Christchurch presently displays a gaping scar of devastated houses that ‘The New Eastside’ provides a bandage and a cure for. Displaced and dispossessed Christchurch residents can be re-housed within a new heart for East Christchurch.

A two-storey house in Avonside Drive with a warped upper balcony. The photographer comments, "This house is on Avonside Drive opposite the Avon River. The land in this area spread laterally and had bad liquefaction of the soil. This caused some houses to sink into the ground, but as the balcony supports did not sink as much the balcony came to rest at a crazy angle".

The Canterbury region of New Zealand was shaken by major earthquakes on the 4th September 2010 and 22nd February 2011. The quakes caused 185 fatalities and extensive land, infrastructure and building damage, particularly in the Eastern suburbs of Christchurch city. Almost 450 ha of residential and public land was designated as a ‘Red Zone’ unsuitable for residential redevelopment because land damage was so significant, engineering solutions were uncertain, and repairs would be protracted. Subsequent demolition of all housing and infrastructure in the area has left a blank canvas of land stretching along the Avon River corridor from the CBD to the sea. Initially the Government’s official – but enormously controversial – position was that this land would be cleared and lie fallow until engineering solutions could be found that enabled residential redevelopment. This paper presents an application of a choice experiment (CE) that identified and assessed Christchurch residents’ preferences for different land use options of this Red Zone. Results demonstrated strong public support for the development of a recreational reserve comprising a unique natural environment with native fauna and flora, healthy wetlands and rivers, and recreational opportunities that align with this vision. By highlighting the value of a range of alternatives, the CE provided a platform for public participation and expanded the conversational terrain upon which redevelopment policy took place. We conclude the method has value for land use decision-making beyond the disaster recovery context.

Global biodiversity is threatened by human actions, including in urban areas. Urbanisation has removed and fragmented indigenous habitats. As one of the 25 biodiversity ’hot spots’, New Zealand is facing the problems of habitat loss and indigenous species extinction. In New Zealand cities, as a result of the land clearance and imported urban planning precepts, many urban areas have little or no original native forest remaining. Urbanisation has also been associated with the introduction of multitudes of species from around the world. Two large earthquakes shook Christchurch in 2010 and 2011 and caused a lot of damage. Parts of the city suffered from soil liquefaction after the earthquakes. In the most damaged parts of Christchurch, particularly in the east, whole neighbourhoods were abandoned and later demolished except for larger trees. Christchurch offers an excellent opportunity to study the biodiversity responses to an urban area with less intensive management, and to learn more about the conditions in urban environments that are most conducive to indigenous plant biodiversity. This study focuses on natural woody plant regeneration of forested sites in Christchurch city, many of which were also surveyed prior to the earthquakes. By repeating the pre-earthquake surveys, I am able to describe the natural regeneration occurring in Christchurch forested areas. By combining this with the regeneration that has occurred in the Residential Red Zone, successional trajectories can be described under a range of management scenarios. Using a comprehensive tree map of the Residential Red Zone, I was also able to document minimum dispersal distances of a range of indigenous trees in Christchurch. This is important for planning reserve connectivity. Moreover, I expand and improve on a previous analysis of the habitat connectivity of Christchurch (made before the earthquakes) to incorporate the Residential Red Zone, to assess the importance for habitat connectivity of restoring the indigenous forest in this area. In combination, these data sets are used to provide patch scenarios and some management options for biodiversity restoration in the Ōtākaro-Avon Red Zone post-earthquake.

The cartoon shows Christchurch obscured by ash. Text reads 'Christchurch recovery package' and below are the words 'Cash cloud'. Context - Beginning on the 6th of June the Puyehue-Cordon Caulle volcano has been erupting for more than a week. Drifting ash clouds have been interupting flights. On Thursday 23 June Prime Minister John Key, Canterbury Earthquake Recovery Minister Gerry Brownlee and representatives from engineering consultants Tonkin & Taylor announced the first part of the Government's long-awaited land report that revealed the fate of up to 5000 quake-damaged homes. These homes were in the 'red zone'. But 10,500 owners in the orange zone were left in limbo, with their properties requiring further assessment. One of the options presented to residents in the red zone, ideal for people with replacement policies, was the government bought your land, and you dealt directly with your insurers about your house. However they got a shock when insurers told them they won't replace their homes, they'll only repair them, even though they're earmarked for certain demolition. Quantity: 1 digital cartoon(s).

Large cracks run through the brick cladding of this house in Wainoni. The photographer comments, "During the numerous earthquakes in Christchurch the land which ran alongside the Avon river on Avonside Drive slumped towards the waterway. Houses which were wooden framed and had an external brick veneer started to sink into the liquefied soil. This caused the brick walls to crack, but the houses' occupants though shook up were saved by the wooden framework from the houses collapsing on them".
