Elusive winning couple Krezentia and Koby Yates thought it was a hoax when they received a bank email telling them to call Lotto.
They waited hours before making the call to find it was no joke - they had won a Winning Wheel draw.
NZ Lotteries tracked the couple through Etfpos transactions and contacted them through their bank.
"We thought it was a joke and then we recognised the name on the letter as someone we had dealt with at the bank," said Krezentia.
"We found the ticket in the study with a pile of old tickets, we ended up sleeping with it under our pillow, it was so exciting."
