From there she runs her online travel agency and he manages his cycle and walking tracks review website.
Now they live the lifestyle they want and own their own home without a hefty mortgage, something they would not have been able to do in Tauranga.
Although Ms Tanner employs two staff in a small office in Nadi, Fiji, she is able to oversee them, update her website and keep an eye on the bookings from her desk in the truck.
"I have two websites and we sell tours, trips and accommodation, airport transfers and activities in Fiji," Ms Tanner said.
"We talk on Viber [similar to Skype], and I can see anything that goes through the booking system as it is all online.
"The only difference between running a business here or in Fiji is I am not there in person."
Ms Tanner’s internet provider gives her 120GB of data for $99 a month.
She chose not to use a satellite but has an $125 aerial, for better coverage.
It is not necessary to use the aerial when they are in Millers Flat as a Vodafone cell tower is close by, but they find it is essential when they travel to more isolated areas.
Her internet mobility allows her to pick and choose her hours of work and also where she works from.
"If Garry says ‘Let’s take the bikes to Lake Onslow’ then we just go," she said.
She can work when they visit Australia or from any place in New Zealand with a suitable internet connection.
She felt lucky to be running an internet-based business, she said.
"We came down to Millers Flat as we could not afford to own our own home in the North Island and we did not want a large mortgage. ‘‘We had our mobile home already and we needed somewhere to park it."
Both outdoor enthusiasts, they had explored Central Otago and decided the region was where they wanted to be.
"It is the ultimate playground," she said.
They eventually bought the cheap section and moved down in March this year.
"Millers Flat is a cute little town, with a small community and very friendly."
The truck has a shower and toilet, foldaway bed, a good-sized kitchen with gas hob, oven and fridge, plenty of storage and a plastic awning to extend their living area when required. They have to take the truck into Roxburgh every couple of weeks, to the dump station, and have access to fresh water when required. They also have a van for when it is not practical to cycle to Roxburgh for groceries or when they need to go further afield.
Although semiretired, Mr Griffiths reviews walks and cycle trails throughout the country, all of which the couple have done themselves.
New ones are added as the couple complete them.
