"We saw online on Saturday night that someone in Timaru had won $7 million, so I thought I may as well check our ticket.
"I honestly never thought we'd win, but in the back of my mind I was thinking 'that would be nice'.
"But when I pulled up the results on MyLotto, I saw we had four numbers in a row and I panicked and turned the computer off.
"I was just so nervous. After a couple of deep breaths, I turned the computer back on and checked the rest of the numbers - and they were all there. My hands started shaking. It just felt so unreal."
The family bought the ticket at Timaru Pak'nSave. They flew to Lotto New Zealand's head office in Auckland to claim the prize.
They intended to use the winnings on several things, including helping family, buying property and travel.
"I'm a huge fan of the Rugby Sevens, maybe I could follow the boys on the 2016 World Series tournaments?
"But right now, we're going to hit the shops!"
