A person who was trapped has now been freed by firefighters following a two-vehicle crash between a logging truck and a car on the Rimutaka Hill, between Upper Hutt and Featherston.

Fire Emergency New Zealand (FENZ) crews were called to reports of a truck versus car on SH2 on the Upper Hutt side of the hill at 6.15am.

One person was trapped when they arrived on the scene and had been since freed, a FENZ spokesman said.

The New Zealand Transport Agency said the crash was blocking the road and advised people to expect delays.
