Ruru, 31, was first introduced to volleyball during her years at Western Heights High School. She moved south to Dunedin to play professional netball with the now defunct Otago Rebels franchise, before moving to Tauranga for a year where she fell in love with beach volleyball.
"That is when beach volleyball really kicked off for me. And then when I joined the police they were very supportive of that. So I thought I will just keep going with it," she said.
She said giving up netball to focus on volleyball was not as tough as people might think.
"I could only do one or the other, and you can't beat travelling the world and seeing all the beaches and being outdoors in the sun, compared to being inside in a gym playing netball."
Ruru explained her dream of competing at the Olympics started about four years ago.
"Maybe around the time of the last Olympics. We were just competing really well against international, professional athletes and I suppose that is what planted a seed about four years ago.
"And I thought I'll see how the next three or four years go and see where I am at injury-wise and how work is, but it has all worked out pretty well."
Volleyball NZ will send Ruru and Bagge to Sydney at the end of this month for a warm-up tournament before the qualifying event in Thailand. Ruru said she and Bagge had been working well together since teaming up at the start of this season.
