Today's aerial search over Mt Owen for missing tramper Alistair Levy did not find any sign of him.
A fine break in the weather in the area in the middle of the day was the first opportunity since Boxing Day that the Nelson Marlborough Helicopter has been able to resume an aerial search.
Mr Levy, 54, has not been seen or heard from for a week, after reaching the 1875-metre summit in Kahurangi National Park last Sunday and sending a text message.
The Palmerston North teacher was to meet up with his wife and family in Christchurch last Monday, but did not arrive and a search began on Christmas Day.
Today Nelson Marlborough Rescue Helicopter pilot Jarrod Colbourne said they left Nelson just before noon to search, returning at 3pm, but did not see any trace of him.
The area they focused was Poverty Basin and Castle Basin which is steep terrain with alpine rock.
It is along Mr Levy’s intended route from an entry he made in the Granity Pass hut book.
The previous aerial search was made on Wednesday and since then the weather over Mt Owen had been cloudy with drizzle.
Cavers have been in the area and also keeping an eye out for Mr Levy.
The police have said they hold grave concerns for him, given the time elapsed since he was last heard from and the challenging terrain.
