The cause of a fire at Whakarewarewa Forest off Sala St on Tuesday is still unknown.
Two fire trucks and a tanker were sent to put it out at 2.35pm. It covered an area about 20m by 30m.
Fire and Emergency New Zealand senior station officer Barry Hogan said the cause of the fire was still being investigated.
"It's a busy time of the year," said Hogan.
"With what's happening in Nelson, it's important for people to check before they light."
