Earlier this year, the Queenstown planner rode his mountain bike the length of the country raising awareness - and $43,000 - for the Motor Neurone Disease Association of New Zealand.
The ride - prompted by his father Barrie, of New Plymouth, being diagnosed with the disease - earned him a medal in the Kiwibank Local Hero Awards.
That was on top of being named a fundraiser of the year finalist in the TSB Bank-sponsored Pride of New Zealand Awards.
Mr Vivian was surprised to get the Local Hero medal.
"It is nice to get a bit of recognition from people that aren't going to directly benefit from what I've done.''
The planner cannot help but be busy.
A building boom is putting a strain on resource management specialists in the resort.
But that has not stopped him planning the next ride which will probably take place next summer, in the Queenstown area.
"It gets a little bit addictive,'' he said.
Once again, he will raise money for the Motor Neurone Disease Association of New Zealand.
"It's a lot shorter - only a couple of weeks - but a lot harder than riding the length of the country,'' Mr Vivian said.
"I'm still working on the logistics.''
Mr Vivian is in New Plymouth this week visiting his father. He recalled when his dad was diagnosed with motor neurone disease he was told to do everything on his bucket list.
That was the seed that grew into his fundraising ride.
Biking the length of New Zealand was on the Queenstown man's personal bucket list, so he put that together with his fundraising idea.
He said the ride from Cape Reinga to Bluff, which started on February 1, was made easier through the kindness of strangers.
People gave him directions as well as donations.
"We only had two days of rain the whole way, perfect weather and hardly any headwind.
"Everything just went very smoothly.''
Mr Vivian throws himself into fundraising and social media.
"It's got nothing to do with my job,'' he said.
"The only thing in common is the people I tell about it and try and get donations [from].''
