Four Australian trampers have spent the night in an alpine shelter on Fiordland's Kepler Track after some of the party became tired.
Department of Conservation senior ranger Ken Bradley, of Te Anau, said the four were ''good as gold'' this morning after their night in the shelter between the Luxmore and Iris Burn huts.
He understood the trampers, who are in their fifties, decided to stay at the shelter after delaying their start from Luxmore Hut because of rain, and were then affected by tiredness.
''They were seen by other people to be a bit slow.
''They've just overestimated their physical capability.''
The group walked to Iris Burn Hut this morning and were continuing on to Moturau Hut today.
Two Canadian men were killed in an avalanche on the Kepler Track in July.
