Wallis said he was fed up with the constant presence of the film crew on the beach, where he has lived for 26 years.
"They harass people. They look for content and dramatise everything," he said.
"Some women don't want to sit on the sand in their togs because the cameras are never far away.
"It would be different if the girl had put her hand up and genuinely needed rescuing. But they were just dramatising a small situation."
The girl was soon pulled to shore by two surfers and her mother, Alex Gard, said she later realised she had panicked.
"Next minute I turn around and there's a camera in my face. I didn't realise who it was or where they were from," Gard said.
She would be embarrassed if the footage was aired, she said.
'"Phil showed her exactly what was going to happen in the rip. He knows Piha like the back of his hand. I have complete faith in him."
Piha Rescue star Duncan Clark said Wallis could get "a bit wound up".
"It's happened several times this year. He feels he doesn't have to inform us when he's doing these lessons."
Piha Surf Club president Peter Brown described Wallis' lessons as "high-risk". He said there had been no problems with Piha Rescue in its eight years filming - apart from incidents involving Wallis.
Brown said the water-safety education provided by the show outweighed any minor inconveniences.
The surf club also received a small payment for its participation in the show and the exposure on prime-time television kept sponsors happy.
TVNZ and South Pacific Video Productions, the company behind Piha Rescue, would not comment.
