The driver of a ute involved in a collision with a tractor has died almost a week later from his injuries.

A black Nissan Patrol ute and a John Deere sprayer tractor collided on River Rd near Port Waikato bridge, close to the South Auckland settlement of Tuakau on Tuesday last week.

Constable Paul Evatt, of the Counties Manukau Serious Crash Unit, confirmed this afternoon the driver of the ute had died in hospital. His name is yet to be released.

The man, believed to be aged in his 20s, had to be cut from the mangled wreckage of the ute and was flown by Auckland Westpac Rescue Helicopter to Auckland City Hospital in a critical condition.


A passenger in the ute received minor injuries while the tractor driver was not hurt.

Police still want to hear from anyone who may have witnessed the crash, which occurred about midday, Mr Evatt said.

Anyone with information should call police 021 192 1527, or anonymously via Crimestoppers on 0800 555 111.
