A search is underway for a father and son who haven't returned from a seven day tramp in Te Urewera, in the North Island.
Police, LandSAR volunteers and a helicopter are searching for the pair in the Waikaremoana and Waiau areas.
The father, who is middle aged, and his teenage son were due to exit the bush at Hopuruahine Landing on Sunday afternoon, but never showed.
The shuttle driver waiting to collect them stayed at the meeting point overnight before reporting the pair missing to police on Monday morning.
The pair were well-equipped for the tramp and the father is experienced, police say.
The search will continue until dark.
