Two groups of trampers have been rescued by helicopter from the Kahurangi National Park at the top of the South Island, after their emergency locator beacons were set off on Wednesday afternoon.
Bad weather forced the Nelson Marlborough Rescue helicopter to wait until Thursday morning to pick up the trampers who had been left stranded after a major slip blocked the Wangapeka track.
The Nelson Marlborough Rescue Helicopter's base manager, Tim Douglas-Clifford, says the groups met at the slip and camped at the top of it overnight after they realised they couldn't get around it.
Mr Douglas-Clifford says the trampers were uninjured but cold.
He says his crew received another beacon activation in the area this morning, but that turned out to be a false alarm.
Major landslips are still blocking the track.
