Police last week seized thousands of dollars worth of kauri gum from a massage parlour in Whangarei. Banana boxes, fish bins and sacks filled mainly with pieces of unpolished gum were found during a search of the Scarlet Lounge on Tuesday, although some of it was returned after it was established that it had been legally obtained.
That left hundreds of kilograms that had allegedly been stolen, however.
Two search warrants were executed, one at the Scarlet Lounge and the other at a property at Oakleigh, south of Whangarei.
Constable Geoff Bigwood said there had been numerous burglaries in Northland over the past 12 months where kauri gum had been targeted. Police knew of about five such burglaries, but there could have been more that were not reported.
"It's a valuable commodity, and we believe it's being exported to the Chinese market," he said, adding that some of that seized had been finished to a high quality.
