Police are seeking witnesses to a shooting at a campsite in Ngawi, South Wairarapa.
The incident happened on the evening of December 16 last year and resulted in a man being shot in the leg.
A vehicle arrived at the Ngawi campground about 10.30pm where at least three male occupants confronted the 46-year-old victim, police said.
After a short verbal altercation a shot was fired by one of the group and the victim received a bullet wound to his thigh.
"We have made good progress and are confident that we will identify those responsible, but we still require some further assistance from the public," Detective Sergeant Bill van Woerkom said.
