Waikato is Lotto's luckiest area with an average $640 won per head last year.
NZ Lotteries chief executive Wayne Pickup said the title was largely due to former Te Kauwhata checkout operator Trevor's $26.5 million Powerball win in April.
Former check-out operator Trevor Lotto Powerball win in April meant $641.50 was won per capita in the Waikato, more than any other district, NZ Lotteries chief executive Wayne Pickup said.
Invercargill was next, with $467.94 won per head, mainly due to a $20 million win in November, followed by Clutha, Tauranga, Napier, Waipa, Grey, Franklin, Taupo, and Stratford.
Recent winners of the title Tararua (2011), Buller (2010 & 2008), and Masterton (2009) didn't make it into the top ten.
