The man rushed to tell his partner who had trouble getting her head around so many numbers on the screen.
"I showed her the picture of my ticket with the prize amount and she just looked at me and said 'what's that - $5500?'. I had to tell her to look again – I guess we aren't used to looking at a number with so many zeros!"
Letting his big win sink in, he went for a walk to get some dinner but the big grin didn't slip off his face.
The couple are still mulling over what to do with their new found fortune, but a house and a new car and helping out the family are at the top of their list.
They are also still coming terms with their win.
"We're not extravagant people and have always been careful with money, so we keep looking at things and thinking 'nah, that's too expensive' – then I catch myself.
"We're going to be pretty sensible with the winnings – it's a life-changing prize and I want to make it last."
The winning ticket was purchased on MyLotto and is the second time a Powerball First Division has been won in just over a week. An Auckland couple won $9m in Powerball. This is the second time in a row the Powerball First Division has been won. A young West Auckland couple won $8 million in the previous week's draw and were also planning to spend some of their winnings on a new house and helping family.
