Nearly 7000 households were cleared off Christchurch's residential red zone.

Parts of Christchurch's red zone could be used to graze dairy cows.

Two proposals by Regenerate Christchurch, the agency looking at future uses for the Crown-owned land, could include grazing, which property valuers determined to be the best financial use of the land.

The value of the red-zoned areas owned by the Government was released under the Official Information Act by Land Information New Zealand (Linz).

GEORGE HEARD/STUFF Regenerate Christchurch chief executive Ivan Lafeta has not ruled out grazing as an option for some areas.

"Linz has determined that the damage to the properties in the residential red zone constitutes full functional loss and that the 'highest and best use' for this land has been deemed to be as dairy grazing," Linz deputy chief executive Jerome Sheppard said.

Jeremy Barr, Linz Canterbury recovery group manager, said this was "purely a mechanism for the purposes of valuation", but didn't rule out any use for the land.

DEON SWIGGS Red-zoned land in Bexley would be worth $37,500 per hectare as dairy grazing land, according to a property valuer.

"This valuation approach does not imply or suggest any future use option for the RRZ land."

Regenerate Christchurch chief executive Ivan Iafeta did not rule out dairy grazing either.

The organisation is seeking feedback on 10 proposed combinations of red zone land uses.

Two of these combinations include areas designated for "productive land uses", which Iafeta said could include dairy grazing.

This month, Regenerate Christchurch published a land use assessment report for productive land use.

It said arable and pastoral farming was not well suited to the area because it was low-lying, close to urban areas, and could have "actual or perceived" environmental effects.

"The only exceptions to this are grazing/finishing and production of baleage, which may offer short-term uses on a leasehold basis to existing operators," the report said.

"Some investment would be required to prepare the land for livestock grazing, including fencing, security and water supply as well as stock handling facilities."

It said the option could be viable for an extended period if more than 200 hectares was made available for grazing."

"However, as such an extensive, contiguous area is unlikely to be available within the Area it may not be possible for the land to support commercial scale pastoral livestock (except for small scale finishing/grazing)."

Regenerate Christchurch will refine its shortlist after receiving feedback on the 10 options.

The organisation will then hold an exhibition with design plans and more details, and seek more feedback before creating a draft regeneration plan for the area.

Based on the land's value as dairy grazing property, real estate consultancy Knight Frank produced price estimates for Linz.

The prices varied a lot from suburb to suburb.

Rapaki and Heathcote Valley red zone land was estimated to be worth $6750 a hectare, while Christchurch Central red zone land was estimated at $47,500 per hectare.

It did not give a total value for the red zone.
