Dannevirke Police Detective Sergeant Graham Perks said the raids, though unrelated, were both the result of information from the public.
"At the end of the day, information the police are told comes in various forms at varying times and this time we just happened to get information on two different growing operations that are completely unrelated."
There were similarities between the operations in terms of sophistication, but the tip-offs were coincidental.
"Indoor growing relies on artificial heat, so in terms of indoor growing there is no real 'time of year'," he said. "It is found at all times of year.
"Outdoor is different as it relies on weather obviously, and we are actually coming into that season, but it was a coincidence that we found these particular indoor-growing operations when we did."
Mr Perks hoped the two raids were sending a strong message to the criminal fraternity.
"Hopefully the message is going out loud and clear that we will not tolerate drugs in our communities and just because your operation is hidden out of sight doesn't mean we won't be knocking on your door."
