"It was luck of the draw."
While Mr Wells' choices failed to survive the weekend, Ms Van Der Werff's picks have kept her in.
"I kind of just went with my gut instinct," she told the Herald.
"I've got Dutch heritage and that's kind of who I backed for a little bit."
She also said her boyfriend had kept her informed about the matches, and admitted she might "have to keep an eye" on what was happening now.
A TAB spokeswoman said if no one won the $5 million, a prize of $1000 each was offered to the five punters with the most guesses right.
