Vincent hasn't had much success with 55 runs at an average of 13.75 and strike rate of 103 in five matches but it is the exclamation mark he brings to his life which makes that mediocre spell of form seem irrelevant.
"Mate, I've just got back from Brendan Taylor's partner's birthday dinner where the cake arrived before half the mains. No one was too worried about it. They're such laid back cats over this way. It was almost expected."
Before long Vincent has vented a stream of consciousness that makes you wonder if the electrons in his brain might consider going on strike.
He's looking at going skydiving when he gets to Nepal; he's enjoyed a slice of pizza with [Zimbabwe under-19s coach and former Black Cap] Chris Harris and his three kids that evening; he's just met Chris Gayle in the hotel corridor and is certain "the coolest cat he's ever met" sleeps 20 hours a day; he can't believe an umpire gave him out the other day to a right-arm off-spinner bowling darts around the wicket when he was sweeping on the front foot.
Such entertainment alone is worth the price of the phone call. Far from being labelled a cricketing mercenary, Vincent is more of a social butterfly. It is a key factor which sustains his career.
"I was talking to the coach of Hong Kong, Charlie Burke, recently over a beer and he asked if I fancied working with the team. So I'm contracted until January, then I haven't got a clue what I'm doing - but I've got used to that.
"I find travelling the world fascinating, seeking knowledge and embracing whatever culture I'm in. Cricket's taken me everywhere and [being batting coach at Hong Kong] means it'll be nice to boss other people without having to stretch all the time. You start to think about those things post-30.
"I could apply for coaching jobs in Zimbabwe, link up with an Asian country, pick up an English county contract or find myself back in Auckland for a couple of games like last summer. Who knows? You can make a decent living out of contracts. I'll be retired by 40, don't you worry about that."
Vincent likes to make sure he sees his Manchester-based daughters Molly and Bessie as often as possible, otherwise he sends them postcards. He spends around five months of the year in England as a result, but the cricket never stops.
In recent years he's played everything from village cricket with the Professional Cricketers' Association side "mingling over a few glasses of wine at a long lunch, first" to donning the whites under the stewardship of the Bee Gees manager, David English, at the Bunburys Club to county matches with Sussex.
There is a serious side to setting up deals.
"There can be a stand off. I like to be paid on arrival, because you risk being shafted. You work out your value and get good at negotiating. You get on the phone, hear the word on the street and make sure the figure's fair.
"I just never want another Indian Cricket League situation. Most of us only got paid three-quarters of those contracts. However, the cricket world's a small place. I'm confident nothing like that will happen again."
Vincent's infectious positivity hid a tough period of depression that he had to battle through after New Zealand Cricket rejected him and the ICL fell through a couple of years back. Vincent has endured. In fact, he is upbeat at what he sees from the next generation of New Zealand cricketers.
"Ultimately I'm pleased with the decisions I made. I don't regret moving on from New Zealand cricket.
"I had a good patch but I'm excited watching the current team. They will have a good core for at least five years," he said.
