The winning connections of Think About It weren’t the only ones who struck it rich in the A$20 million The Everest (1200m) at Randwick on Saturday, with one New Zealand punter earning $10 million after correctly predicting the finishing order.

The punter was the sole winner of the Everest Mega Millions promotion run by TAB NZ.

The successful punter said he "didn't put too much thought" into his picks after seeing the promotion online.

The competition was available to all NZ TAB account holders, with the payout covered by insurance.

“I’m absolutely blown away," the punter said.

"I saw the promotion on the TAB site and thought I’d give it a crack. I didn’t put too much thought into my picks and just dropped the runners where I thought it could go.

"I honestly could not believe I’d won it. I actually thought it was a hoax when they first rang me – I called the TAB back, and it took quite a lot of convincing before it sank in.

To have pulled it off, winning $10 million in a free to play competition, is truly incredible for my family and I.”

Managing Director of Entain New Zealand (operator of the TAB), Cameron Rodger said: “It was great to see so many Kiwis getting involved in The Everest through our Mega Millions promotion, and to have someone take home the $10 million prize is an amazing result.

"The Everest is the world’s richest race on turf and this customer has managed to take home more than the winner’s purse by pulling off one of the most impressive selecting feats we have ever seen.

"The race had over 400 million possible finish results, and he managed to nail the exact one needed. We’re thrilled with the customer engagement this innovative competition was able to generate and a huge congratulations to our winner.”
