Easing winds and some overnight rain has helped to contain the large scrub fire in Pukaki Downs, near Twizel, Fire and Emergency says.

On Thursday night a convoy of about 50 vehicles - containing mostly tourists - left the Aoraki Mt Cook area, with nobody endangered by the large fire which began on Wednesday night at Pukaki Downs.

Fire and Emergency incident controller Stephen Butler told Morning Report that about 10.4 millimetres of rain had fallen at Pukaki and the winds had died down.

Butler said 42mm of rain had fallen at Glentanner.

"That's huge relief for us. The best thing about that for us is that the cloud's actually quite high so we have got a chopper in the air this morning with our operations manager doing a fly over so that we can get situation awareness of what's actually happening before we have our briefing at 7.30[am].

"The fire is looking a lot better than what it was yesterday."

The conditions would be assessed for safety before ground crews were sent in, he said.

Heavy machinery would be working on stop points throughout the fire to protect homes.

Helicopters would operate weather permitting.

Butler said about 180 hectares have been burnt so far, but no homes have been damaged.

"The locals have done a fantastic job of giving themselves some defendable area around their homes as a result of the fires three years ago so we've learnt from that and they've now got nice manicured lawns in front of their

homes and we've cut down trees that were too close to their houses."

State Highway 80 from Pukaki to Mount Cook reopened Friday morning through Butler said people need to be cautious and maintain situational awareness when travelling.
