Police say a six-month covert operation targeting meth supply in Central Hawke’s Bay and Hastings has resulted in three arrests and the seizure of methamphetamine, cash, a 3D-printed firearm and stolen property.

The operation, codenamed Operation Tukutuki, followed sustained wastewater testing that indicated high meth use in parts of Hawke’s Bay, Detective Inspector James Keene said.

On Wednesday 10 December, officers executed five search warrants across the district. Keene said several warrants were run at the same time to protect the element of surprise and prevent suspects tipping each other off. He said further charges are expected and more arrests cannot be ruled out.

Three men — aged 39, 42 and 57 — were arrested. Police say two are patched Mongrel Mob members and the third is a Mongrel Mob associate. All three appeared in the Hastings District Court on Wednesday 10 December facing multiple charges, including possession for supply, supply and conspiracy to supply methamphetamine and cannabis.

The 39-year-old was remanded in custody to reappear in the Waipukurau District Court on 12 January. The 42-year-old was remanded in custody to reappear in the Hastings District Court on 19 December. The 57-year-old was remanded in custody to reappear in Hastings on 23 December.

Police pointed to the latest wastewater testing results and asked anyone with information about drug supply or other criminal activity to contact 105 online at 105.police.govt.nz or by phone. Information can also be provided anonymously via Crime Stoppers on 0800 555 111.
