The prize money had not been claimed at edition time yesterday. Two other players from Taranaki and Amberley each won $333,333 in Lotto first division on Wednesday night.
Bayleys Northland general manager Tony Grindle said any number of things could be done with such a whooping amount of money.
"It depends on what the winner invests the win on. Is it on a business investment to generate money or just on lifestyle, vehicles, charity and giving some to family and friends that winners typically do these days?
"You could buy the Marsden Estate Winery and live at The Landing where Barack Obama and John Key stayed recently. You could also buy two or three 1000-acre dairy farms or commercial buildings," he said.
The asking price for the winery in Kerikeri is $4.2m and the package consists of land and buildings, restaurant, vineyard and on-site winery known for its award winning Black Rocks chardonnay, pinot gris and rose. It also has room for expansion of the vineyard and comes with a three bedroom, two bathroom private apartment on site.
The three-bedroom, two-bathroom villa on The Landing is going for upwards of $3m.
The winner could also buy two $4m, limited edition Aston Martin One-77s - which is being touted as the most expensive car for sale in New Zealand - with money left over for petrol to run it.
The other big Powerball wins in Northland over the years were $8.2m in 2001 (Shell Kensington), $5m in 2016 (Sunnyside Foodmarket in Whangarei), $4.3m in 2004 (Keyman Whangarei) and $3.3m in 2002 (Mags n More Dargaville).
The biggest Powerball prize ever won in New Zealand was $44m by a Hibiscus Coast couple in November 2006. The winning ticket was sold at Dairy Flat Food Mart & Liquor in Auckland.
