The Lotteries Commission is waiting to hear from the person who won more than $15 million in the latest Big Wednesday draw.
Both the first and second division tickets were sold at the Karamu Road Caltex station in Hastings.
New Zealand Lotteries Barton-Chapple said it's highly likely both tickets were sold to the same person and together are worth $15.4 million.
Spokesperson Victoria Barton-Chapple said it could be someone passing through on holiday who has not realised yet, or a person who's still processing the win.
She said $15 million is a life changing amount and often winners don't want to claim the prize locally.
Staff at the Caltex station hope the ticket was sold to a regular customer.
Manager Mitesh Chaudhary said the win is great news - not just for the customer, but also for Hastings and his petrol station. He hopes the winner is someone they know.
Ms Barton-Chapple said the last big lottery win was in September when a man won $27 million.
