Lake Ōhau Village residents hugged each other and cried as they returned from their first visit to the area after a fire ripped through 1608ha and destroyed up to 50 properties.
The residents boarded a bus early on Monday afternoon to tour the village, which one local described as "completely unrecognisable".
After returning to Twizel Events Centre from the trip, Dwayne Rennie, the co-owner of The Barn At Killin B&B, said it was "like a bomb had gone off".
An emotional Rennie described seeing metal twisted by the heat of the fire.
Others described a "tangled mass of corrugated roofs" and "cars that look like a Molotov cocktail exploded inside them".
Fire and Emergency's Graeme Still said this afternoon that he was "quietly confident" the Lake Ōhau fire, which broke out early on Sunday morning, was contained.
Still said it was the worst fire in terms of property damage he has seen in his 40 year career and about 40 houses have been left "uninhabitable".
Fire crews were maintaining a perimeter around the blaze.
Media were taken on a tour of the devastated town. Many houses have been reduced to blackened shells, while others have been spared and appear untouched by the blaze.
After authorities earlier confirmed that between 40 and 50 homes and structures were destroyed in the village in the Waitaki district, Civil Defence Minister Hon Peeni Henare gave an update on the situation this morning after seeing the devastation for himself.
Henare and Conservation Minister Eugenie Sage described seeing cars which had tyres completely melted off and burned-out houses.
"What we have just witnessed is completely devastating for the people of this community," Henare said.
He said there was no "rhyme nor reason" about the devastation, with houses completely destroyed while neighbouring houses escaped unscathed.
Henare announced the Government had provided $100,000 to a mayoral relief fund as initial support to those affected.
The ministers and Waitaki District Mayor Gary Kircher thanked firefighters and Civil Defence staff for the work they had done.
As of midday today the fire had burnt 4600ha, of which 1900 is conservation estate. The fire had a perimeter of 41km.
Eleven helicopters and eight ground crews are fighting the fire today.
Despite the challenging conditions, with strong winds and warm temperatures, Hands said he was confident that crews would have achieved 50 per cent control of the fire perimeter by tomorrow night.
That would place a 10m boundary of cold ground around the fire along half of its perimeter.
Residents woken by blaze
Devastated residents evacuated the normally idyllic lakeside village after being woken by a massive blaze early yesterday.
About 90 people were forced to sleep away from their homes overnight after they were destroyed in the 1608ha fire, which began about 3.15am yesterday, and destroyed much of the village.
Officials confirmed earlier today that between 40 and 50 homes and structures were destroyed.
"We can confirm that between 40 and 50 structures are uninhabitable, pretty much destroyed ... and about 40 that are as good as gold. There's a more detailed assessment that has to be done but that lifts that number up," Fire and Emergency's Mike Grant told TV1's Breakfast programme.
Kircher told RNZ's First Up programme this morning it was lucky residents got out when they did.
"The reality is it's a minor miracle that no-one has been harmed, if it had been another 15-20 minutes it would have been a very different story."
MetService duty forecaster Tui McInnes said that the winds around Ohau would strengthen today and it wouldn't be until tomorrow some "rain spillover" was set to hit the area.
Still said there were no injuries or loss of life as residents and visitors in up to 70 homes were forced to flee.
More than 100 people had registered at an evacuation welfare centre operating at the Twizel Events Centre.

Sixteen crews worked to steer the fire away from other structures and critical infrastructure, including the main power lines servicing Queenstown and Wanaka.
The scenes on the ground looked "like a war zone".
Lower temperatures and easing winds overnight would provide some relief, he said.
The Barn at Killin B&B owner Hugh Spiers described the horror of being separated from his father in the dark while driving through the "terrifying" blaze.
Spiers said he received a phone call about 3am warning him and his guests to get out urgently.
"It was like the movies. It was really, really scary.
"The flames were big and smoky, thick with heat - there was no time to even take a photo.
"We couldn't get out our normal way - we had to cross country through a fire break."
Spiers reconnected with his father, and all his family and guests were accounted for.
Dunedin resident Andy Winneke woke to dramatic views across Lake Ohau yesterday.
Winneke and his family were camping across the lake and after "a fairly sleepless night" due to high winds he saw the beginnings of the blaze about 4.30am.
"I was happy to be at a distance," he said.
Network Waitaki chief executive Geoff Douch said it was too early to tell what might have sparked the blaze.
He had heard no reports of downed or damaged power lines.
"Last night we had extreme winds in the area, an unprecedented level of winds," he said.
"We've had to isolate power out of the whole Ohau area, for safety and so that fire services can safely put out the fire."
Kircher said the mood at the welfare centre was tense at times.
"It is a very stressful time.
"There's a lot of people feeling very stressed and upset as you'd expect and part of that is that for some it's that they know their house is gone, and for others they just don't know yet and it's a pretty hard wait until they do find out."
Three large fires in South Island
The Lake Ohau fire was one of three large fires in the South Island yesterday.
A large pine forestry fire also broke out about 3.15am in the settlement of Livingstone, about 30km northwest of Oamaru.
