Police in Nelson have released an identikit picture of the man who beat and sexually assaulted a 62-year-old woman at the city's Victory Community Gardens on New Year's Day.
The woman suffered substantial injuries in the attack.
Police have described her attacker as Maori or Polynesian and about five foot six inches tall, with a short "number three" haircut.
He has distinctive tattoos described as tribal in style on both arms.

A freephone number has also been set up for people to call with information.
That number is 0508 2674662.
