Police have made a further arrest in the homicide investigation into Bay of Plenty man Clifford Umuhuri's death on 1 June.

Detective Inspector Lloyd Schmid says this morning members of the enquiry team, assisted by the Armed Offenders Squad, executed a search warrant at a Druces Road, Wiri address where a person of interest was located.

This man, a 30-year-old, has been spoken to by police and has now been charged with the murder of Mr Umuhuri.

He is due to appear in the Auckland District Court this afternoon.

Today's arrest follows an earlier arrest this week as part of the investigation.

Lloyd says the enquiry team has worked extremely hard over the past fortnight as they pieced together the events which led to Mr Umuhuri's death.

Despite the fact an arrest has been made, this work continues and further charges may be laid in the matter.

Police are still appealing for sightings of the silver Nissan Skyline vehicle of interest in the case early on Monday, June 1.

Lloyd says this vehicle travelled from St Johns to the vicinity of Symonds Street and Whitaker Place.

This vehicle has travelled from St Johns Road, along Ngāpipi Road, Tāmaki Drive and Quay Street towards Whitaker Place between 6am and 6.24am on June 1.

'We are exploring the possibility that this Nissan Skyline has stopped briefly on the route.

'We need anyone who saw this vehicle or any suspicious activity along this route to contact the enquiry team.”
