Napier residents have been warned to expect heavy traffic tomorrow as police monitor the funeral of a prominent gang member with "significant community links" which is set to take place tomorrow.

A large number of mourners have travelled into Hawke's Bay for the funeral on Saturday afternoon, police said.

Hawke's Bay Area Commander Inspector Lincoln Sycamore said police have continued engagement with the community, gang leaders and members, as well as the deceased's whānau over the past few days.

"Our role remains to give mourners the respect and space to grieve, while also enhancing public trust and confidence and upholding the law."

The deceased will lie in Percy Spiller Ave in the suburb of Maraenui overnight ahead of a funeral at the Napier Tech clubrooms at 1pm, followed by burial at Wharerangi Lawn Cemetery off Prebensen Dr from 3pm.

Police said locals should expect "heavy traffic" as people travel between these locations.

"The deceased's whānau have a Traffic Management Plan in place, and Māori Wardens and contractors will be assisting with this to ensure it runs smoothly."

Sycamore said there will be "no tolerance" for breaches of the law, including the Gangs Act 2024, nor any unsafe or intimidating behaviour.

"If police are not able to deal with breaches at the time, efforts will be made to follow up after the fact."
