Expectations for a proposed ban on heli-hunting on conservation land are up in the air following lead advocate Peter Dunne's resignation as a cabinet minister.
The United Future leader stepped down over the GCSB leak inquiry, leaving Conservation Minister Nick Smith to lead the fight against the controversial hunting practice.
Mr Dunne has previously promised legislation to ban it altogether.
Heli-hunting involves helicopters locating game animals, dropping hunters into wilderness areas for short periods and sometimes herding or 'hazing' the animals. The practice has long angered traditional hunters in South Westland.
Opponents complain about cruelty to animals, the noise of the helicopters, and heli-hunters being dropped close to campsites on blocks balloted to ground hunters.
