Firefighters from rural New Zealand are flying to Canada to help battle blazes raging in almost 800,000 hectares of forest.
The western Canada wildfires have forced thousands of people to evacuate and thick smoke has triggered air quality warnings across the country and into the United States.
One of the fires was more than five times the size of Saskatchewan's largest city Saskatoon, officials said.
New Zealand rural fire officer Kevin O'Connor said 16 firefighters were leaving Auckland for Canada on Tuesday.
The firefighters would fly into Vancouver before transferring to Edmonton in Alberta to start an expected five-week deployment providing frontline support to local firefighters, he said.
