"The ongoing value of the land is significantly reduced due to earthquake damage.
"In order to aid recovery and support the objectives of the residential red zone process, it has been decided to also make an offer to the owners of these properties."
The Government has already sent offer letters to owners of 6479 insured residential properties on the flat land in greater Christchurch, including 15 insured residential properties under construction and five insured properties owned by not-for-profit organisations.
Mr Brownlee confirmed that owners of uninsured houses are in the same situation as owners of vacant land, and will receive the same offer of 50 per cent of the rateable value of their land.
"If owners decide to take this offer, the land and any buildings on it will become property of the Crown from the settlement date," the minister said.
"What the owner chooses to do with any buildings on the land up until that day is entirely up to them."
Similar properties in the Port Hills will be addressed at a later date, he said.
Owners of vacant land will be required to settle within six weeks of accepting the Crown offer or April 30, 2013 (or June 30, 2013 if the property is located in Southshore), whichever occurs first.
The final settlement date for all other categories of properties will be April 30, 2013 for most areas, with the Southshore red zone being June 30, 2013.
