Three tourists who have spent the night stranded in Fiordland National Park have now been rescued.

The trio radioed authorities about 10pm last night when the weather deteriorated in the Emily Pass area.

A helicopter was initially deployed but could not reach the walking party because of low cloud and strong winds.

However, police confirmed at 7.40am today that the weather cleared enough for a helicopter to fly to the scene and rescue the women, who are all overseas visitors aged in their late 20s.

All are safe and well, police said.

They were equipped for a day tramp and not an overnight stay.

A helicopter dropped two LandSar members nearby, who then walked the cold trio to a sheltered area and stayed with them overnight.

Rescue co-ordinators are waiting for a break in the weather before considering when to send a helicopter to pick up the party.
