Volunteer firefighters had to jump on a private boat to get to a blaze started by an illegal campfire on a Bay of Islands nature reserve.
The alarm was raised by campers on Urupukapuka, the largest island in the Bay of Islands and home to rare birds such as the saddleback, about 11pm on Saturday. It is understood the fire was lit by other campers at Cable Bay.
Members of the Rawhiti Rural Fire Party used a boat to get out to the island, which is about 1km from the mainland.
Rural fire boss Myles Taylor said the blaze was almost out when volunteers arrived, but it was a foolish thing to do given all the work Project Island Song had done to replant the island and reintroduce native wildlife.
"For someone to risk all that was very irresponsible," he said.
