Christchurch quake: 10,000 homes 'cannot be rebuilt'
New Zealand's Prime Minister John Key has said 10,000 homes in Christchurch cannot be rebuilt after the 22 February earthquake. He also announced a national memorial day of 18 March, with events planned for Christchurch's Hagley Park. On Sunday the treasury department said that quake recovery would cost the country NZ$15bn ($11bn; £7bn). The death toll, at 166 so far, is expected to rise to around 200 as rescue work continues.
