Tasmania's Rebecca Van Asch is now a triple world champion.

The lawn bowler from Invermay Bowls Club rolled her way to her second gold medal at the World Bowls Championships in Christchurch, adding the women's triples title to the women's fours crown she picked up earlier in the tournament.

Alongside Jackaroos teammates Carla Krizanic, from Sunbury in Victoria, and Natasha Scott, from Raymond Terrace in NSW, the trio controlled the final against Wales to give the Australian team another win at the 34-nation tournament.

"We were pretty well in control, judging by the score, but I assure you when you're out there playing it doesn't always feel like that and we knew we had to keep our head down to make sure we didn't let them back in the game," Van Asch said.

"We came in with the aim of wanting to get a good start on them and that's exactly what we did and we kept them to nil for quite a few ends and it was sort of a dream start to things for us.

The 28-year-old Tasmanian said she was thrilled with the way she had played on the biggest stage.

"It's been a lot of hard work leading up to this point and it's great when a plan comes together I guess," she said.

"It's very hard just to win one world title and I achieved that four years ago and to back it up now and have three is an absolute dream and an honour."

"We came over with the goal of coming away the number one country in the world and we've now secured that."

Back in form after 'grit and grind'

After becoming the first Tasmanian to win a world title in 2012, Van Asch went through a form slump, dropping out of the national side completely.

"Two years ago I missed out for selection for the Glasgow Commonwealth Games and obviously that was a setback for me personally and for my career and I was out of the Australian team for just over two years and was battling with some poor form," she said.

"It's been a lot of hard work and a lot of grit and grind from my point of view and I just kept my head down and I always had the confidence and belief in myself that I could get back and I suppose that makes this a little bit sweeter because it hasn't been an easy few years."

She now has her sights set on gold at the Gold Coast Commonwealth Games in 2018.

"I guess that elusive Commonwealth Games title is certainly there and I haven't been able to secure it," she said.

"I haven't been able to get to a Commonwealth Games so that's my motivation now ... and I'll be working my butt off in 2017 to try and put my best foot forward for selection for that."

Only two female players, Australia's Karen Murphy and Ireland's Margret Johnson, have won more world championship gold medals, putting Van Asch among the elite of the sport.
