New Zealand's police minister is warning that the major gangs are now working together in Auckland to push drugs to increasingly middle class customers.
Judith Collins has told ONE News that the Head Hunters gang is using the Mongrel Mob and Black Power to distribute methamphetamine.
"It's a gang-led invasion of people's homes and people's lives," Ms Collins said.
"Gangs are working together now in prisons and out of prisons for a particular cause and that's making a lot of money."

Ms Collins said the gangs are pushing the drug to middle class Kiwis and have even made moves to get school children using meth.
"It's a situation where a lot of middle class kids who go to the best schools are being targeted because their parents have a lot of money."
Ross Bell from the drug foundation said Ms Collins' statement does not match with the statistics on methamphetamine use.
He said meth use has halved in the past four years.
Mr Bell also said that the majority of users of methamphetamine are 25 to 35-year-olds.
