Police have recovered a body from a vehicle off State Highway 2 north of Wellington today.

A police spokesman said police were not sure of the sex of the person due to the state of decay.

It looked like it had been there for a few weeks, he said.

The vehicle had been found down a bank off the Rimutaka Ranges.

Police spent the early hours of this morning recovering the body after receiving information it was there, Detective Sergeant Steve Harwood of Lower Hutt police said.
