Mental Health Foundation chief executive Shaun Robinson said the Motorally Aotearoa riders epitomised the values of MHF fundraisers.
"They are committed to the cause, have set themselves goals, and are driven to make change to the wellbeing of all New Zealanders," he said.
"I really admire the work they have put into the campaign to spread the word of positive wellbeing, as well as having fun at the same time.
"These riders are demonstrating wellbeing in action. They're taking time away from their usual routines to join together with a common goal that will no doubt present challenges, but together they will be supporting each other and learning about their own wellbeing while exploring Aotearoa."
One of the riders is Westpac NZ chief executive David McLean, who will be stopping in, with the group, at branches on the way.
"I use my Vespa most days around town in Auckland, but it'll be a new experience taking it for such an extended run on the open road," he said.
"We're taking time to do something that we love and to connect with people, and that's what mental health means to me. This is about reminding one another that our mental health matters, as much as, if not more than our physical health. It's something we all need to think about, talk about, and work on," he added.
"It won't be an easy ride. Vespas are marvellous machines but designed for trips around Rome or Milan. Their urban suspension – and our backsides – will be tested out on the open road."
