Christchurch Airport says it will review its noise restriction plans in light of an announcement that 860 homes in Kaiapoi will have to be abandoned.
Residents were told on Wednesday their land has suffered so much earthquake damage their houses are uninhabitable.
Waimakariri MP Clayton Cosgrove has raised concerns that the airport's planned restrictions could create a barrier to red zone residents wanting to stay in the area.
Mr Cosgrove says the airport's intention to lower noise restrictions in its flight path would have meant new developments could not be built where levels exceeded 50 decibels.
He says he has created a members bill that aims to keep the restriction at the nationally recognised 55 decibels.
The bill would also give the airport security by making it impossible for people building in the flight path to object about future expansions due to noise.
