Canterbury Earthquake Recovery Minister Gerry Brownlee has released the parameters of a review of zoning decisions for people living in the Port Hills.
The move follows a similar review for those on flat sections who wanted to challenge geotechnical data used to decide how badly damaged their land was following recent earthquakes.
The Port Hills review will look at the risk to life posed by falling rocks and slips which threaten a property.
The review will not include the ban the Christchurch City Council has placed on some from re-entering their homes due to the threat posed by falling rocks.
Residents have until 26 October to apply for a review and decisions are due by December.
The Labour MP for the Port Hills electorate criticised Mr Brownlee for not opening up a review of zoning decisions to all people whose properties are affected by rockfall and slips.
Ruth Dyson says the council and the Canterbury Earthquake Recovery Authority need to work together so that all of those affected have some certainty about the risk to their properties.
