We're told that New Zealand's obesity problem is not going away anytime soon and the front line is often said to be in south Auckland, where fast food joints rule and places to exercise have traditionally lagged behind.
But one man, affectionately known as Mr Tee, is determined to change that one person and one bike at a time.
His reason is a personal one - after suffering high blood pressure, breathing problems, sleep apnea and Type 2 diabetes in 2012, he decided he needed to change.
He's since lost 100kg and his initiative Bike Fit has been running for almost a year. Bikes are donated to Mr Tee, and he fixes them up and gives them away to kids, teaching maintenance all the while.
He's a man on a mission and Story met him at Mangere Town Centre, where he's encouraging anyone and everyone to get on a bike.
