Gang tensions: ‘Off the scale’ drug supply and social media posts spark ‘dangerous’ confrontations

  • There have been two months of clashes between Mongrel Mob and Black Power gangs in Hawke’s Bay and Gisborne.
  • One gang source told the Herald he believes rogue behaviour has been inflamed by an influx of meth.
  • Police say the violence – including houses being shot – is putting lives at risk, and some serious incidents aren’t even being reported.

Drug use and provocative Facebook posts are behind the recent violent clashes between Mongrel Mob and Black Power members along the North Island’s east coast, according to a gang source.

Two months of flare-ups between gang members and associates in Hastings, Napier, Wairoa and Gisborne saw police issue a Gang Conflict Warrant in the Eastern District in April.

A Gang Conflict Warrant gives police special powers to search vehicles of suspected gang members and to seize firearms, weapons and vehicles.

Police say they are carrying out a “significant operation” in response to the escalating rivalry, which has included houses being shot at in Wairoa, gang associates gathering around a home in Napier, vehicles being rammed and other acts of violence not officially reported.

Things don’t happen out of nothing. If you are using meth, you are ... in a heightened state of arousal, therefore more likely to do outrageous things

East Coast gang source

But a well-placed gang source told the Herald that while the incidents involved gang members, the tensions were not part of a turf war between rival gangs and were not ordered by gang leadership.

“I could say that with some confidence,” he said.

Instead, he believed members and associates – some under the influence of methamphetamine – were acting independently of gang leaders.

Gang associates going rogue

That included a stand-off outside the Napier home of a gang leader the source said was sparked by online comments made by the man’s niece about a rival gang.

“A young woman from up the line put some stuff on Facebook and stirred some s*** down here,” the gang source told the Herald.

“Then all these young fellas turned up at the house of her uncle and that blew up into a bit of a scene. There were young fellas, mainly in their teens, in and around a suburban house.”

Police have not spoken about what they believe has sparked the outbreak of violence in the Hawke’s Bay and Tairāwhiti regions.

But they have called for the “unsettling and frightening” scenes to end, and are working with gang leaders to calm the situation.

The role of methamphetamine

The gang source said some of the incidents were fuelled by methamphetamine.

He said drug supply in the regions was currently “off the scale” fuelled, he claimed, by shipments coming in from North America, South America and Asia.

“That is more likely to explain some of the behaviours” he said.

“Things don’t happen out of nothing. There is some causal behaviour there. If you are using meth, you are more likely to be in a heightened state of arousal, therefore more likely to do outrageous things.”

In just two months, Customs has halted the importation of at least 220kg of methamphetamine - and it’s anyone’s guess how much of it successfully got through.

The drugs had originated from North America and Malaysia. One of the busts had a street value of almost $20 million.

Since the beginning of 2025, Auckland Airport staff have seized an estimated 405.69kg of drugs across couriers and baggage.

Results of the Gang Conflict Warrant

Police confirmed they have arrested and charged several people with drug possession and other drug-related offences on the East Coast since invoking the Gang Conflict Warrant.

Detective Inspector Dave De Lange, of the Eastern police district, told the Herald officers were taking a zero-tolerance approach to illegal gang-related activity across the region.

“We will not tolerate this dangerous and disruptive behaviour, and we are continuing to commit significant resources to holding gang members accountable for their actions,” De Lange said.

“The recent uses of the Gang Conflict Warrant have given us greater ability to undertake activities which have led to numerous arrests.”

De Lange said dedicated police staff were working directly with Mongrel Mob and Black Power gang leaders in response to the outbreak of violence.

Police told the Herald they were also aware of a number of serious incidents in Wairoa that had not been reported to them.

They include assaults, vehicle rammings and other threatening behaviour.
