A patched Mongrel Mob member from Tauranga is one of nine people arrested and charged in a drug bust that netted more than $300,000 worth of drug making chemicals.

The 30-year-old man is due to appear in Tauranga District Court today facing numerous drug charges after being arrested in Tauranga this morning.

He is one of nine people facing charges including the supply of methamphetamine, importation and supply of pseudoephedrine in the form of ContacNT following an investigation by the Organised and Financial Crime Agency of New Zealand.

Operation Gull centred on a 20-year-old Asian student who is facing multiple charges of supplying in excess of 560 grams (20 ounces) of methamphetamine during a 3 – 4 month period to people living in the Auckland, Tauranga and Hamilton areas.

It is alleged that this 20-year-old student was supplying methamphetamine to his co-offenders, including the Tauranga man, who are then alleged to have on-supplied the methamphetamine to others.

The other eight people including a 29-year-old man from Auckland, who is a prospect for the West Chapter of the Head Hunters gang, and three others with connections to either the Black Power or Tribesman gangs were arrested last month.

Five have been remanded in custody.

As a result of the investigation approximately 130 grams of methamphetamine valued at around $91,000 and approximately $130,000 in cash was seized.

A further 6.6kgs of ContacNT valued at around $290,000 was also seized with 2.2kgs by police at a South Auckland address and 4.4kgs by the New Zealand Customs Service at the Auckland International Mail Centre.
