Police boosted in Whanganui as 'large number' of gang members arrive for tangi

Police numbers have been boosted in Whanganui as a "large number" of gang members gather in town to mourn shooting victim Kevin Ratana.

The 27-year-old, who was a Mongrel Mob member, was shot dead in his home in Castlecliff last Tuesday morning.

A tangi was held for him on Monday morning at a marae in Parikino, as the homicide investigation into his death continues.

Whanganui Area Commander Nigel Allan estimated around 100 gang members had arrived in the city and there would be "high visibility policing" over the next fews days.

Police officers across the lower North Island and an Eagle helicopter have been brought in, while gangs across the town were fortifying their bases, Area Commander Allan said.

"As police it's our job to respect and protect rights of everyone, regardless of their background - so part of our objective as well is to work with the gangs, so they can grieve with the whanau."

There have been no reported incidents, but Commander Allan said a presence is necessary to try to prevent any further tension between gangs and to reassure the community.

"We have a capability here in the city, if something does happen we'll be able to respond appropriately."

He said locals should go about their lives as normal and should not feel afraid.

Earlier on Monday morning, there were a number of search warrants executed across the city in relation to the homicide investigation, and a number of streets were cordoned off.
