"He certainly regrets putting his family and friends through the stress. That would have been foremost on his mind," she said. "He's a very kind, hard-working young person who enjoys life. He has paid a price and learned a lot from this. He wants to put it behind him and move on."
Bennett says her son is back in New Zealand, returning to a promising landscape and design career and may embark on a university degree next year.
Japanese media quoted police as saying Price threw a plastic bag containing white powder away before trying to flee officers.
Another family member, who asked not to be named, said it was not uncommon for Europeans to be randomly searched by the secret police in Japan and Price stood out, at 1.87m with blond hair.
He said Price received a suspended sentence that took into account time spent in prison. "He received three feeds of rice a day and showered twice a week. He's made an error of judgment but he's had a long time to think about it."
Bennett said her son started modelling after being spotted a couple of years ago.
"He's happy to let that go for a while and to look at his future."
