Their team managed four fires called the Birch Complex totalling about 83,000ha spread across about 200sq km about 100km away from their base.
Mr Ihaka said flying crews and resources to and from fire sites due to no vehicle access was a challenge.
"One of the things that gave us problems was the rain. Thunderstorms were relatively frequent so the accessibility of getting people to and from the fire sites was reduced.
"We've had to constantly monitor the weather. There were a couple of new fires in our area which we had to get to pretty quickly."
Mr Ihaka said it was the first time New Zealand had sent a complete management team and he was satisfied of the job the kiwi firefighters performed as coordinators.
"The Canadians were pretty tired and worn out and the purpose of us going was to give them some rest. It's still happening in British Columbia ... it's not over yet for those guys," he said.
Mr Ihaka said there were 230 firefighters from Canada, Australia, United States and New Zealand in camp during the first set of fires and about 100 later on.
He spent the first few days getting his head around what was happening on the ground.
Although he had fought larger fires in Australia, Mr Ihaka said the geographical spread of the Canadian fires made them tricky to fight.
And apart from a bear roaming near their makeshift tents early in their deployment, Mr Ihaka said there were no issues from their stay.
