Police are appealing for help from the public after numerous reports of traffic offending following a large Hawke's Bay tangi for a senior Mongrel Mob member.
Hundreds of gang members joined the procession on State Highway 2 on Tuesday afternoon after a service was held at Te Kura Kaupapa Maori o Ngati Kahungunu ki Heretaunga.
Hawke's Bay area commander inspector Lincoln Sycamore said police are appealing for the public's help after the tangi caused "significant congestion" on SH2, south of Pakipaki.
Sycamore said after monitoring the situation, a team has been dedicated to follow up reports of various traffic offences including dangerous driving and sustained loss of traction (burn-outs).
