One person has died after a bus went off the road on State Highway 1 at Hikurangi, near Whangārei.
Sergeant Lance Goulsbro said the Ritchies bus was heading south towards Whangārei when it appears to have hit the roadside barrier before it rolled off the road and landed in a shallow stream about 5 to 6metres below a bridge.
The male driver was the only occupant of the bus at the time.
A police spokeswoman said officers were notified of the incident near Piano Hill Rd around 4.30pm.
"There were no other vehicles involved," she said.
