One person has died in a crash involving a ute towing a caravan in Omarama.

Emergency services were called to the single-vehicle smash on Twizel-Omarama Rd, at 12.30pm.

A police spokeswoman said another person was injured and needed treatment.

The road will be closed and motorists should expect significant delays.

"Please continue to avoid the area and consider delaying travel."

A Fire and Emergency New Zealand spokesman said two crews free the trapped occupants of the ute.
