New Zealand has a long tradition of using light timber frame for construction of its domestic dwellings. After the most recent earthquakes (e.g. Canterbury earthquakes sequence), wooden residential houses showed satisfactory life safety performance. However, poor performance was reported in terms of their seismic resilience. Although numerous innovative methods to mitigate damage have been introduced to the New Zealand community in order to improve wooden house performance, these retrofit options have not been readily taken up. The low number of retrofitted wooden-framed houses leads to questions about whether homeowners are aware of the necessity of seismic retrofitting their houses to achieve a satisfactory seismic performance. This study aims to explore different retrofit technologies that can be applied to wooden-framed houses in Wellington, taking into account the need of homeowners to understand the risk, likelihood and extent of damage expected after an event. A survey will be conducted in Wellington about perceptions of homeowners towards the expected performance of their wooden-framed houses. The survey questions were designed to gain an understanding of homeowners' levels of safety and awareness of possible damage after a seismic event. Afterwards, a structural review of a sample of the houses will be undertaken to identify common features and detail potential seismic concerns. The findings will break down barriers to making improvements in the performance of wooden-framed houses and lead to enhancements in the confidence of homeowners in the event of future seismic activity. This will result in increased understanding and contribute towards an accessible knowledge base, which will possibly increase significantly the use of these technologies and avoid unnecessary economic and social costs after a seismic event.

With many in Christchurch still living in earthquake damaged houses, the cold snap has prompted a call for temporary emergency shelters. Daphne Lewis-Mannix lives in a quake-damaged home in New Brighton. Her power was out last night, and she's been shivering overnight, already sick with a cold before the storm hit.

Damage to a house in Richmond. A brick chimney has visibly twisted and there are gaps between the bricks. The photographer comments, "Damaged chimney. We'll have to get this taken down tidily, but our roofer friends are a bit busy... (It was taken down on the morning of Day 2, just as well)".

A digitally manipulated photograph of a letterbox lying on the ground in front of a red-stickered house. The photographer comments, "An abandoned red stickered house just outside the four avenues that surround Christchurch CBD. The letterbox came down when the wall it was attached to collapsed. The occupants would have had strict instructions to stay out as the property is too dangerous to enter in case there is another earthquake or big aftershock".

People stand in front of a damaged house in New Brighton. The upper storey at the front of the house has collapsed onto the floor below. The photographer comments, "This house at 158 Marine Parade, New Brighton, Christchurch was owned by the man leaning on the fence. He lived next door and his daughter lived here. During the earthquake the 2nd storey stayed mainly whole, but the 1st collapsed. Luckily the daughter was in the top storey. She was rescued from the building by neighbours, by climbing out of the window and down a ladder. Another piece of luck is that most of the belongings were stored in boxes in the garage at the front. Though the garage also collapsed the boxes appear intact. The owner had tried to sell it previously without success".
