Two Southland firefighters are in New South Wales helping out with the fires.
The pair are part of a group of six deployed last week to support the firefighting efforts there by working on heavy machinery and in safety roles.
Another 21 firefighters from New Zealand, though none from the South, left yesterday to help with wildfires in Queensland.
Fire and Emergency New Zealand (Fenz) has formal arrangements in place with Australia, the United States and Canada and co-ordinates wildfire deployments when one of those countries asks for help.
A spokesman said the six sent to New South Wales were specialists helping in air attack and heavy machinery supervision, safety, and managing interstate deployments.
Large wildfires have been burning in both Queensland and New South Wales for the past nine weeks.
The New Zealand contingent of six three-person crews, two task-force leaders and a liaison officer will begin operations in Queensland today.
As of Monday, there were 50 active bushfires in Queensland and a state of fire emergency has been called.
''Fighting fires of this magnitude is a hugely demanding task and we're happy to provide support to our Australian colleagues,'' said Paul Turner, national manager response capability.
''They're tough firefighting conditions over there at the moment. The hot, very dry and windy conditions are causing extreme wildfire behaviour.''
The New Zealand crews operating in North Queensland would be working up to 14-hour shifts for two five-day rotations.
Over the past 19 years, Fenz has deployed 986 people overseas, 140 of them in the past 12 months to Australia. Since 2000, we have deployed 26 times to Canada, United States and Australia.
