Nepia pointed out trust in one another was a key ingredient to her team's success during the weekend's 45th annual tournament which attracted 56 men's and 42 women's teams.
"Everyone did their job and nobody growled. Sharon was awesome and put no pressure on me ... she was so composed," Nepia said of multiple world champion and 2002 Commonwealth Games gold medallist Sims.
"I wasn't going to play in the tournament because our Bay View club was one of the host clubs and I thought I would be working behind the scenes. My clubmates encouraged me to enter and I'm glad I did. We will be back again with the same team next year with the aim of going back-to-back when the tournament is played in Taranaki," she added.
Nepia's team collected four on the final end to pip the Tamaki Makaurau team of skip Chingy Tate, three Sophina Ngaika, two Maria Taka and lead Shirley Taipari 8-7 in their semifinal. The other women's semifinal saw Meredith's team beat Tamaki Makaurau's two-time winner of the title Doreen Jensen and her team of three Karen Hema, two McKenzie Blucher and lead Lavinia Ruka 10-5.
A Kahungunu women's team of skip Gaylene Harvey and three Natarsha Grimshaw of Bowls Hastings and Wellingtonians, two Tanya Wheeler and led Kaaren Guilford, the defending champions, missed out on a berth in the championship section on a countback of two ends to Jensen's four after Saturday's five qualifying games.
The men's final saw a Whanganui-a-Tara team of skip Richard Morgan, three Wayne Armstrong, two Bob Thomas and lead Danny Madden beat a Waikato team of skip John Kawana, three Tony Parkinson, two Hopa Bell and lead Merv Gibbons 13-8.
Picking up four on the seventh end to take a 9-4 lead was the key to Morgan and co's $2000 collect.
In the men's semifinals Morgan's team pipped another Whanganui-a-Tara quartet of skip Mike Solomon, three Matt Hunter, two Lee Hunter and lead Pat O'Neil, a late replacement from Bowls Hastings, 8-7 with one shot on the final end and Kawana's team beat Marshall Tyson's Whanganui-a-Tara team which also included three Mark Morete, two Ian Hartley and lead Rawiri Shetlock 9-6.
Another Kahungunu women's team of skip Tash Haronga, three M J Rickard, two Diane Durham and lead Joni Hakopa won the second flight. Nepia's Bay View clubmate Wayne Parker skipped a Kahungunu team of three Joe Johanson, two John Garnham and lead Jim Cornish to victory in their second flight final against the Whanganui-a-Tara quartet skipped by Ray Lovie which won last year's championship title.
