A 53-year-old man has gone missing in Tongariro National Park.

A police communications spokesman said emergency services were alerted at 5.30pm yesterday.

Police and Land Search and Rescue members from the central North Island continued the search on Mount Tongariro this morning.

Police say four men set out at 8am yesterday to hike over the Tongariro Alpine Crossing from Ketetahi to Mangatepopo.

The group stayed together until the bush edge below Ketetahi Hut, where three of the men continued without the missing man, police say.

Police were notified the man was missing by his wife when he did not return to his vehicle around 5pm.

The search continued until after midnight in blizzard conditions without success and reconvened at 7am today.

A helicopter was also called to help with the search.
