Canterbury Earthquake Recovery Minister Gerry Brownlee delivered the news this morning in the last of eight announcements about the rezoning of more than 150,000 houses on flat land in greater Christchurch over the past 11 months.
Today's decision affects 401 properties in Southshore West. The owners of 198 properties found out their homes were red-zoned and are eligible for a Government offer of purchase.
A recently announced change to the offer period means they will have a year from the date on the letter to select an option and return the sale and purchase agreement to the Crown.
The remaining 203 properties in Southshore West have been zoned green and owners can begin repairs or rebuilding.
The Canterbury Earthquake Recovery Authority will hold community meetings with all residents affected by today's announcement.
"Earthquake support coordinators and the Red Cross will be visiting all rezoned properties in the Southshore West area today, and will leave further information at those properties where no one is home when they visit,'' Mr Brownlee said.
The total number of red-zoned homes in the city is 7256.
Mr Brownlee also announced that 421 homes in the Port Hills had been zoned green, leaving 1679 under review.
He said the announcement was part of an ongoing programme to determine risks from rockfall and cliff collapse.
And he said a through review of the land in Parklands East following the December 23 aftershock has shown the original decision to zone the area green remains appropriate, despite further liquefaction.
