Enquiries were continuing in order to identify the owners of the stolen property, and further charges are likely to be laid, Mr Tieman said.
He said anyone wanting to share information with police about the stolen property and drugs could do so confidentially by contacting their local police station, or by calling Crimestoppers on 0800 555 111."
And in the Waikato yesterday, search warrants were executed on properties by 40 police at Te Aroha, Paeroa, Matamata and Waiuku, as part of an anti-meth operation.
Two shotguns were recovered in the raids.
Nine arrests were made and more are likely, Detective Senior Sergeant Mark Greene said.
"Operation Daydream was focused on the dealing of methamphetamine in and around Te Aroha, alongside dishonesty offending in the same area."
Mr Greene said a man and woman found in a vehicle behind a service station in Bombay overnight were among those arrested.
Others have been charged for offences including dishonesty offences and the supplying of methamphetamine.
"Investigations to date lead us to believe that many of those arrested are known to each other, and they have worked as a group supplying the drug in and around Te Aroha."
