Pink said the deadline ended at 6.30pm on Friday and after asking once, visits would begin to those who hadn't gone.
The source said five or six P dealers left without a fuss, while the remaining few were given a "hand."
"When it's time to go, it's time to go," he said.
"Those that listened were escorted out. Those that didn't were handled and escorted out. There are no more P dealers in Ngaraz."
Pink has previously used violence to shut down meth dealers after his daughter, a young teenager at the time, and her friends were offered the drug in 2007, it was reported.
He told a community meeting in the town: "For a lot of years, the Huks have kept a lot of other gangs out of here in Ngaruawahia and we are always going to do that, but we haven't kept their poison out of here.
His gang had zero tolerance for the drug and did not use nor sell it.
Waikato District Mayor Allan Sanson told the Herald he didn't support having drug dealers in town either, but he also didn't condone acts of violence.
He said: "I do support that message. Anybody that sells drugs needs to leave town as far as I'm concerned. They're not welcome in our community. They just prey on the weak and vulnerable."
He denied that the town had a P problem.
"I have seen no evidence of it, it's not to say it's not there though. What Jamie said last night revolves around Jamie's world. In Jamie's world, P maybe an issue. But in most of the community, it's probably there no different to any other community in New Zealand.
"It sits in the underbelly and you've got to realise that Jamie is part of an organised group that don't have a great reputation around criminal activity."
However, he admired Pink and his gang for his efforts in feeding schoolchildren.
