The operation followed reports of illegally sourced stone from the area being sold commercially and an ongoing investigation to track those responsible, said Corner.
Police had been working closely with Poutini Ngāi Tahu.
Iwi chairs had welcomed the continued support and ongoing investigations, said Corner.

“The public are allowed to fossick for pounamu in approved areas, but this quantity can only be described as commercial.
“Education and knowledge is important. We work with Poutini Ngāi Tahu to help people understand what is permissible.
“But when it comes to what we’ve found here, it’s very different to someone fossicking freely on a beach. This is large-scale theft.”
Police have filed charges of theft against a 50-year-old male and a 42-year-old female from Tarras, and a 62-year-old woman from Jackson Bay.
They are due to appear in the Greymouth District Court on April 29.
