Two missing rafters have been found safe and well on Sunday after a party of nine had earlier gotten into trouble on the Hutt River.
The group had been rafting on a private trip in the Akatarawa Valley, near Upper Hutt, on Saturday when they got into difficulty, police say.
One person was able to raise the alarm at about 8:40pm, with a rescue helicopter finding six more rafters shortly after in a steep gully on the riverbank.
"Due to the nature of the terrain, landing the helicopter was not possible," Life Flight helicopter crewman Julian Burn said.
"All six were winched on board the helicopter uninjured."
An aerial and land search for the two missing rafters resumed at Sunday's first light.
However, the pair had gotten out of the water and followed a track overnight to a car park where they were met by a police unit on Sunday morning.
The pair were fit and well, police said.
