A second man has been arrested following the death of Cedric Maniapoto near Raglan last week.
It comes just two days after a 29-year-old man was charged with the murder of Maniapoto, who was found dead at a property on Ōhautira Rd on Tuesday, March 5.
The 35-year-old man arrested has since been charged with unlawful possession of firearms after appearing in the Hamilton District Court on Thursday.
Acting Detective Inspector Andrew Saunders said on Friday that police are now focusing on the movements of two Toyota vehicles of interest.
"The first is a black Toyota Hilux ute with the registration number EBM957 and the second is a red Toyota Camry with the registration SB857."
Det Insp Saunders asked the public to contact police if they saw the Hilux ute or Camry between 10pm Tuesday 5 March, and midday on Wednesday 6 March.
"We are particularly keen to hear from people who were in the vicinity of East Street in the early hours of Wednesday 6 March," he said.
"Dashcam footage is exceptionally helpful, and we encourage anyone that has a dashcam and knows they were in the area around these times to check and provide anything of note to Police."
In addition to the two vehicles, detectives are trying to piece together what happened to Maniapoto's dog, Napier.
Napier was found about 7am last Tuesday, near a store in Te Uku with gunshot wounds - about an hour before Maniapoto was found.
Police are mystified as to how Napier got there.
"We are still interested in any information that can clarify how he came to be there," said Det Insp Saunders.
The public can contact police by calling 105, or going online and referencing file number 240305/1701. Alternatively, people can call Crimestoppers anonymously on 0800 555 111.
