About 21 tourists are holed up at a lodge in Milford Sound after a huge rockfall on Milford highway cut off the township.
The New Zealand Transport Authority (NZTA) said the road between Falls Creek and Monkey Creek was closed on Friday afternoon and it was not expected to reopen for several days.
Rocks as large as 200 tonnes cover at least 200 metres of the road, which was closed before the slip took place.
Milford Sound Lodge manager Emma France told NZ Newswire six people were flown out by helicopter on Saturday morning and a small plane could be chartered to fly the others out when the weather cleared.
"At the moment we're all running around trying to sort everybody out but there's the local pub [for guests to entertain themselves] and they're putting on some special `road closed dinners'," she said.
English tourist Les Swift, 57, said the poor weather was disappointing but he was enjoying himself.
"We're stuck for the present time so we're heading out walking now," he said.
The highway is the only road into the popular tourist destination and this is the third time it has been closed during the winter season.
Contractors with large rock breaking equipment and a 40 tonne excavator are on standby to help with the clean-up.
