Canterbury reached the imposing tally on the back of a Debbie Hockley hundred and quickfire half-centuries by Jo Lawler and Nicola Payne at Hagley Oval yesterday.
Hockley anchored one end reaching 117 from 143 balls with eight 4s while Lawler contributed 58 from 54 balls with six fours and Payne a similarly speedy 56 from 49 balls with three fours.
Otago was unable to match that run rate and was never in contention reaching 143 for nine from its 50 overs with only Rowan Milburn and Erin Kelly, from Christchurch in her senior provincial debut, making much progress.
Hockley and fellow opener Paula Flannery added 74 for the first wicket. She then teamed with Lawler to plunder 107 in 59 minutes and then 98 with Payne in just 59 minutes. The high scoring contrasted with the low-scoring struggle the previous day when the two sides met at Rangiora's Dudley Park. On a wicket which had been covered after drizzle the previous day Canterbury, sent in by Otago, was restricted to 173 for nine.
It was in trouble at 71 for five the wicket offering the bowlers assistance until Lawler and Helen Watson came together adding 53 for the sixth wicket to push Canterbury toward a defendable tally.
Otago also struggled against the Canterbury attack being dismissed for 96 with only Rachel Pullar unbeaten on 26 making much headway. Hockley contributed with the ball capturing three for six.
Canterbury's brace of wins leaves it equal second on the table in pursuit of Auckland which has now finished its campaign after twice beating Central Districts in Auckland.
Points, with games played in parenthesis: Auckland 12 (8), Canterbury 6 (4), Wellington 6 (6), Otago 4 (6), Central Districts 0 (4).
