Fullarton and her team deal with all of the big winners including the woman who this week discovered an eight-month-old $1 million winning Lotto ticket in her glove box while cleaning her car.
"Most people are pretty overwhelmed when it's a big Powerball prize, so we try and engage as early as possible. The first step is claiming their prize. The word most commonly used with winners is 'surreal'."
'Life-changing'
"It takes a wee while to process, the massive change they are going through. It's life-changing but it does throw people off a little. The biggest thing is that we are there and we are the only people that they will speak to about their winnings, who have no personal interest in it."
The team guides winners to pathways of seeking financial advice and makes an obligation to the winners to keep their identity a secret.
There are no statistics about how many Māori have struck it big but Fullarton says that, anecdotally, she's seen and dealt with many Māori who have called to claim their prize.
"We give out only generic descriptions, like 'an Auckland man' or a 'Temuka woman'. They want to stay anonymous so we want to keep all of their personal details private. We walk with them to craft a story about the feeling of winning but don't talk about the individuals involved."
The largest Lotto win in New Zealand was in 2016 when a couple from the Hibiscus Coast won $44 million.
"Kiwis are so grounded. They've found that they've won all this money and they are super excited. But the first thing that they jump to is: What does this mean for their whānau and their community."
