Bruce Janes, of Loburn, and his crew will fly to New South Wales on Wednesday to support the firefighting efforts there.
The group will act as a burning crew, Mr Janes said.
"We will be lighting up the vegetation ahead of the fire to rob it of fuel.
"It is a bit of a riskier undertaking because you're adding more fire to fire so they have asked for a crew with a high experience level of burning."
He said he is feeling nervous about heading across the Tasman this time, in spite of doing 10 deployments to Australia throughout his career.
"It's just the scale of this one and the fire behaviour we are going to be running into.
"Very dangerous, the most dangerous fire we will have tackled and we are gonna be right in the thick of it."
The 58-year-old is the principal rural fire officer for North Canterbury and Selwyn.
He registered his interest to be considered to help with the bushfires.
"You have to meet a few conditions and once all your pre-requisites are done, then you just sit in a pool of names and they just pluck people from the big list for a particular job."
At least 23 people have been killed since the bushfires in Australia began in September.
More than 1500 homes have been destroyed and hundreds of thousands of people have been affected by emergency evacuation orders.
Up to half a billion animals have also been killed.
