Police investigating the death of Rei Marshall in New Plymouth earlier this month are appealing for information over the movements of a damaged car.
Three men have been charged with murder in relation to Marshall's death.
They want to hear from anyone who saw a grey/silver Mazda Axela hatchback, with a damaged or missing front driver's side headlight, near the foreshore, East End playground, and Pig-out Point about 7pm on Wednesday, 3 August.
"We are also seeking information about any suspicious activity by people along the walkway crossing the bridges over Te Henui Stream, near the bowling club and croquet club around the same time," said detective inspector Brent Matuku.
"In particular, we are interested in sightings of a distinctive orange puffer jacket (pictured) in the area."
Hed said the Police National Dive Squad had been searching the stream and had recovered several items of interest to the homicide investigation.
"We are interested in anyone who may have seen any unusual or out of place items discarded in this area late on the evening of Wednesday, 3 August or on the morning of Thursday, 4 August," Matuku said.
Police are asking anyone with information to call them on the dedicated phone number 0900 287 453.
