Australia is contributing 56 firefighters and Mr Ihaka said both country's firefighters were expected to work together on the ground in the US.
The Kiwi firefighters leave for the National Interagency Fire Centre in Boise, Idaho, where they will be briefed and deployed to Washington, Montana, California or Oregon.
"A lot of fires have started at once and that has stretched resources. It's been a bad season for them," Mr Ihaka said.
"Soldiers are being brought in to help out and we've worked with soldiers before. Our role is mostly supervisory and my job is that of a division supervisor who'll be guiding a group of firefighters on the ground."
He said being a trained firefighter with a history of going places at short notice, he was ready for another overseas deployment this weekend.
"It's the pinnacle of any firefighter to undertake such tasks at short notice. It's what we've been trained to do as fires are becoming a regular event these days."
At the moment the assignment is for two weeks that could be extended by a further fortnight.
"Kiwi firefighters are likely to be working in rugged and mountainous terrain in very high temperatures gripping those states at the moment."
Almost two dozen fires are blazing in Washington state alone.
The US government has mobilised 400 active soldiers to join firefighters and has also deployed four air tankers.
