Hundreds of hopefuls are queuing outside lotto stores around the country

Today is on-track to be the busiest day in Lotto NZ history, with more than 1.9 million tickets already sold for tonight's 50-million-dollar Powerball Must Be Won draw.

Greerton Lotto Owner Belinda Sands says there's a common theme when it comes to how everyone would spend the money.

She says it's not the sort money you'd keep, it's money you'd share and use to help people.
