His first national interview took place near Whangārei – on the top of Mt Manaia – with Radio NZ's Kim Hill.
"Listeners could hear a mad old woman cursing me – I only had one hand on the cellphone for most of the interview in case I had to fend her off. She was mad, but impressive ... and blog views went into the thousands."
To help finance the trek, Chapple began writing articles.
"I was just about a vagabond," he recalls, "sleeping in public toilets on wet nights and asking for donations. My family and I were made very poor by that 5-month tramp and I couldn't have done it without the support of my wife [Miriam Beatson]."
He met every mayor on the route, as well as every landowner.
"It was very personal," he says of turning up to farmhouses. "I'd have a cup of tea with the farmers and get to know them. That was valuable later on."
A $30,000 grant in 2002 enabled him to design and walk the South Island trail – "and I suddenly had a credit card that worked".
Te Araroa trail was officially opened on December 3, 2011 with Chapple's guidebook published at the same time. After standing down as the trust's chief executive in 2012, Chapple received an ONZM.
Why do people tackle Te Araroa?
"Some people are walking towards something and some people are walking away from something. Lots of people want to prove something to themselves or change something in their lives, while some are looking for a good adventure.
"But I walked to make the trail come true."
