It could be up to 18 months before 660 Christchurch homeowners know who will pay for earthquake damage repairs with a $1 billion price tag. The bill to fix houses in Christchurch that weren't repaired properly the first time round, or have suffered more damage in aftershocks, is climbing - and the government can't say who's liable. The problem is the homes have new owners who can't claim on theri insurance because the damage pre-dates them owning the home. Earlier Greater Christchurch Regeneration Minister Megan Woods told us the previous National government put no plan in place, and the current government is being left to pick up the pieces. Former Christchurch earthquake recovery minister Gerry Brownlee disputes the issue.

During the recent devastating earthquakes in Christchurch, many residential houses were damaged due to widespread liquefaction of the ground. In-situ testing is widely used as a convenient method for evaluating liquefaction potential of soils. Cone penetration test (CPT) and standard penetration test (SPT) are the two popular in situ tests which are widely used in New Zealand for site characterization. The Screw Driving Sounding (SDS) method is a relatively new operating system developed in Japan consisting of a machine that drills a rod into the ground by applying torque at seven steps of axial loading. This machine can continuously measure the required torque, load, speed of penetration and rod friction during the test, and therefore can give a clear overview of the soil profile along the depth of penetration. In this paper, based on a number of SDS tests conducted in Christchurch, a correlation was developed between tip resistance of CPT test and SDS parameters for layers consisting of different fines contents. Moreover, using the obtained correlation, a chart was proposed which relates the cyclic resistance ratio to the appropriate SDS parameter. Using the proposed chart, liquefaction potential of soil can be estimated directly using SDS data. As SDS method is simpler, faster and more economical test than CPT and SPT, it can be a reliable alternative in-situ test for soil characterization, especially in residential house constructions.

ACT leader Rodney Hide stands alone in the middle of a blasted plain that was once the 'Christchurch CBD' and says 'A level playing field, excellent. Now we can leave the rest to the market'. Context - Christchurch after the earthquakes of 4 September 2010 and 22 February 2011. ACT explicitly promotes a free market philosophy - a (literal) level playing field in the Christchurch CBD sounds like an excellent opportunity to test the powers of the free market.

USAR codes and a yellow sticker can be seen on the doors of a damaged building. The yellow sticker was part of a building assessment system used following the February earthquake and indicates that this building has limited access and needs further evaluation.
