The $44m won by the Hibiscus Coast couple was New Zealand's biggest Lotto win.
The next-highest was $33m won by a self-proclaimed "westie" in September 2013, and $33m won by a 10-person syndicate in Taupō in September 2017.
Lotto said South Island gamblers were on a winning streak in the first seven weeks of this year, winning five big prizes following on from a $17.1m Powerball win by a Twizel punter just after Christmas.
The big jackpots in recent years have lured New Zealanders into gambling much more on Lotto, pushing Lotto turnover up by 40 per cent from $894m in 2014-15 to $1.25 billion in 2017-18, the latest data available.
About 55 per cent of the amount gambled in 2018-19 was paid out in prizes. Taxes took a further 11 per cent, retailer commissions and operating costs took 6 per cent each, and 22 per cent ($261m) was distributed to community groups such as charities, sports and the arts.
