Family birthdates have been revealed as the secret to success for Tauranga's $500,000 Lotto winner.
The woman, who wanted to remain anonymous, has been playing the same lucky numbers since Lotto started 30 years ago. She won the first division windfall in Saturday night's live draw.
"I chose them quite some time ago. They're mainly family birth dates - all numbers that are special to me," she said.
The winner was watching the live Lotto draw on Saturday evening and marking her numbers off one by one, when she realised just how lucky she had become.
"I couldn't believe my eyes - there they were, all in a row. I called my husband over to come have a look and he was so shocked that he couldn't say a word. I've never seen him speechless before so I took that as a good sign that we had won!"
