Northland's Emergency Services Trust has bought a third rescue helicopter to serve the region.
The trust, which flies about 600 rescue and ambulance missions each year, has been operating two large American-built Sikorsky helicopters.
It has now bought a third Sikorsky to keep pace with what it says is a growing demand for its service.
Trust chair John Bain says safety inspections take each helicopter out of service for up to five weeks, so now there will always have one available with winch capability.
At times when all three are operational, he says, the trust will make one available for flight training, which will help to offset the purchase cost.
