The winner of Saturday's record $28.7 million Powerball jackpot has come forward.
NZ Lotteries announced on its Twitter website that someone had contacted them about the prize about 1.40pm today.
"Who's just been talking to someone who won $28 million? Oh wait, me! Still to officially claim, looking forward to hearing more from them,'' NZ Lotteries said in the tweet.
Lotteries spokeswoman Kate Richards confirmed the winner(s) had called and had the right serial number.
They were yet to claim their prize officially, Ms Richards said.
"They are just so shocked, they are trying to get their heads around what has happened,'' she said.
She said the commission they knew very little about them apart from the fact they had the winning ticket.
The $28.7 million ticket was sold at the Papakura Mobil On the Run 24-hour service station and it took 16 weeks of jackpotting for the mammoth total to be reached.
It is the biggest single Powerball prize to be won in New Zealand.
