Police have busted a massive cannabis growing operation across two houses in the ritzy Auckland suburb of Ōrākei.

One house police were seen at this morning has a council valuation of $3.12 million. The other was valued at $2.52m.

The garage at one house was filled with a metre-high pile of cannabis plants. Police were putting the plants into a truck waiting in the driveway.

At the other address, officers were dismantling and taking away ducting and air filters along with light fixtures, electric fans and reflective material.
