It's been nearly five days, and still the winner of the fourth largest ever Big Wednesday First Division has yet to come forward.
The ticket, sold at Countdown Pukekohe South, reaped $20.2m with a payout for the first two divisions. Division 1 paid $20,048,756, with the winner also getting a division 2 prize of $197,319.
The total is still $16 million short of the $36 million won in Masterton in 2009.
It is unknown if the ticketholder has checked their ticket.
Lotto spokeswoman Emilia Mazur confirmed today that the winner had still not come forward.
