A husband and wife have been identified as the two people involved in a fatal quad bike accident in Northland this morning.
The couple, in their 60s, were travelling along Bay View Road, in Kellys Bay, when the accident happened just before 10.30am.
The Auckland Westpac Rescue Helicopter crew said the couple's quad bike had rolled about 20 metres down a bank.
Emergency services were called to the scene, where the man died.
His wife was airlifted to the Northern Base Hospital in a critical but stable condition, a spokeswoman said.
The accident happened near a camping ground in Kellys Bay, on the Kaipara Harbour south of Dargaville.
A spokeswoman at the Kellys Bay Camping Reserve confirmed the couple had been staying at the camp, but did not want to comment further.
It is understood the pair were regular visitors to the camp ground.
A resident in nearby Kellys Bay Road told the Herald police were still at the scene of the accident, which is thought to involve two adults.
"We haven't heard anything, but police are still there. We're just keeping well away,'' she said.
Police said they were still waiting for an update from officers on the ground. The somewhat remote location of the accident meant there would be some delays.
