What started as a police search for a missing man ended in the discovery of a fully operational methamphetamine laboratory hidden in a hut in secluded Northland bush.
The alarm was raised when police received a missing person's report early Saturday morning.
Acting Detective Senior Sergeant Mark Dalzell said family of the 52-year-old man told officers he had not been seen since going into bushland in Russell State Forest last Wednesday night.
His vehicle was found at a property on the outskirts of the bush.
Dalzell said the Search and Rescue and other specialist police groups were swiftly called out to the forest to try to locate the man, and during their search, officers found a methamphetamine laboratory, camouflaged in a hut in the forest.
