A syndicate of 11 is believed to have won Saturday's $580,000 Pick 6 jackpot.
A TAB spokeswoman said its help desk yesterday received an inquiry as to "how they get paid".
The caller said the winner was a syndicate of 11 and would be collecting the winnings at a Waikato pub TAB
at Ngatea, 23km southwest of Thames, today.
"It's going to be cashed at Ngatea but we don't know if it was sold there," the spokeswoman said.
It was not known how much the syndicate spent.
But it was confirmed that there was only one winning ticket and not a number of percentage bets that totalled one unit.
The Pick 6 dividend of $584,492.70 was the second biggest single payout by the TAB.
The biggest was $628,172 which went to an Auckland dairy owner on a Pick 6 in 1990.
A total of about $420,000 was spent on Saturday's Pick 6 which had not been struck in four previous weeks.
The task of selecting the winners of the last six races on the Auckland Racing Club's programme at Ellerslie looked like being relatively easy when the first two legs were both won by the favourites.
Wings Of Fire won the first leg at a win dividend of $4.35 and carried 169,255.12 Pick 6 units.
That number was reduced to 54,659 units when Waitoki Dream, a hot favourite at $2.60, won the second leg.
But the next two legs were both upsets.
Millennium returned a win dividend of $13.15 in the third leg in which he was the sixth favourite of eight runners.
That left 2326.88 live units.
The fourth leg was won by $20.35 outsider Hot Elle who reduced the Pick 6 units to 115.44.
There was a reprieve for punters when the second favourite, Hoof'n It, paying $3.75, won the fifth leg which left 37.14 units going into the last leg.
All but one of the 11 horses in the last leg were covered.
The winning ticket was on Vice Versa who paid $29.60 for a win and was the ninth favourite in the 11-horse field.
