NZ Lotteries' chief executive Wayne Pickup said the lucky winner increased their prize from $10,000 to $400,000 thanks to the must be won rule if First Division is not won the prize is added to the next highest division where there are winners.
In this case there was no first division winner and therefore the jackpot rolled down to second division where there was just one winner.
"This prize will have come just at the right time for this winner with Christmas just around the corner, they will be able to treat themselves quite a bit more this year," says Mr Pickup.
Bullseye is a daily jackpotting game which gives players a chance to win up to $100,000 every day by simply picking a six-digit number between 000,000 and 999,999 if their number exactly matches the winning number, they've hit the Bullseye.
The jackpot can reach a maximum of $400,000 before a must be won draw is called.
"Anyone who bought their ticket from this store should write their name on the back of the ticket and check it immediately at any NZ Lotteries' outlet or online at MyLotto," Mr Pickup added.
