A New Zealand woman leading Victoria's bushfire response says the deadly blaze
is poised to become ''one large megafire''.

Victorian Country Fire Authority deputy chief officer Dr Stephanie Rotarangi left her role as Otago Principal Rural Fire Officer in 2016 to head across the ditch, where her agency manages 1200 career fighters and about 60,000 volunteers.

As part of the bushfire response, she has also been serving as Victorian state response controller, working with all emergency agencies.

At least 25 people and millions of animals have died as a result of the fires since September.

Rotarangi said Victoria was one of the most bushfire-prone places in the world.

''We are dealing with agencies and communities that are well used to dealing with fire.

''But the scale and significance of these fires is unprecedented for us as a state, and us as a country. We're really working with quite new fire behaviour.''

While Rotarangi was managing the state response, her husband, former Dunedin
firefighter Anthony Rotarangi, was battling the blaze on the frontline.

While conditions had improved slightly over the past couple of days, both strong winds and high temperatures were forecast for Friday.

There were 1.2 million ha of fire in Victoria as of yesterday afternoon.

''We're very much planning for a response that will last until end of April,'' Dr Rotarangi said.

''The fires are of a size where they're all starting to merge, and there is real concern that the south-eastern part of Victoria will end up with one large megafire.''

She said she had been overwhelmed by the support from New Zealanders, and those in Otago.

Her work in Otago had also helped in her new job, she said.

''There are a lot of skills I learned in Otago that have been really beneficial to my role now.''
