Four players remained in each division after the preliminary rounds.
In the ladies’ semi-finals, Treloar beat her 14-year-old granddaughter Sophie Haskins 10-6 while Pauline Stone led throughout for a comprehensive 12-2 win over Tina Smith.
In the final, Treloar rallied from 6-0 down after three ends against Stone to tie it up at 8-8 after the ninth end. She then picked up two shots in the extra end to win 10-8.
Having had to settle for runner-up on five occasions in previous year, Treloar was particularly happy with this victory – her 21st Poverty Bay-East Coast Indoor Bowls Centre title in total.
In the men’s semi-finals, Doc Tipene pipped Dylan Foster 7-6 after some great draw bowls kept Foster from gaining the shot in an extra end.
Matthew Foster collected a four in the seventh end of his semi-final to seal a 10-5 victory over David Lynn.
Foster continued his excellent form with a decisive 10-3 defeat of Tipene in the final to secure his third title in this event and 23rd centre title overall.
