Mr Mahima woke at 5am and was frantically flipping through channels to catch the news. Finding nothing, he headed to whanau hotpools where people told him about Vili's success.
Vili's 17-year-old sibling Lisa Adams, who also lives in Rotorua up the road from Vivian, was also camped out in her lounge. But missing from watching the spectacle was dad Sidney, who died of stomach cancer last year.
Vili's achievements are testament to the type of person she is, Lisa Adams said. "She's a strong woman. We all lost our dad last year. He would have been proud of her."
Vili dominated the competition right from her first throw of 20.56m, a mark none of her competitors, including Belarussians Natallia Mikhnevich and highly rated Nadzeya Ostapchuk, could overhaul.
Mikhnevich took silver with 20.28m and Ostapchuk threw 19.86m for bronze. Vili was so good she didn't need to throw her last shot put.
"I saw her first throw. That was a PB, that was pretty good," Lisa Adams said.
"I was thinking she was going to win, I just wasn't saying it. I didn't want to jinx it."
