The win in August saw a young woman from Auckland become an overnight millionaire, pocketing $11.5 million just as the city entered alert level 4 lockdown.
At the time, the woman told the Herald she didn't realise she had won even after seeing an email from Lotto the morning after the draw, and initially thought her prize was just $11,500.
"It was unbelievable. My sister and I just sat in the car screaming – it was such a cool moment," said the woman who did not wish to be named.
On Saturday two tickets shared Lotto First Division after a computer-generated draw, but neither of them had the $20 million Powerball number.
Strike Four was also won on Saturday - that ticket collecting $200,000.
Some stores are closed due to Covid-19 restrictions, and live Lotto draws cannot take place while Auckland is in alert level 3 because they do not meet the Health Ministry's Covid-19 safety guidelines.
