Martin Guptill's scintillating innings made light work of a challenging chase as Auckland cruised to a five-wicket win over Canterbury in Christchurch. Canterbury's start was thwarted by the loss of their openers before Peter Fulton and Johann Myburgh steadied the ship with a 93-run stand. Scott Styris accounted for Fulton when he was a shot away from his half-century, but Myburgh had set his sights on a big innings. Craig McMillan provided the impetus with a typically belligerent 57 that included five fours and two sixes. The fifth wicket raised 90 in 73 balls before McMillan's dismissal triggered a flurry of wickets that denied Canterbury the finishing flourish. Myburgh was run out off the penultimate ball of the innings for 112, setting Auckland a steep chase of 283. Guptill, however, was intent on making it a no-contest and took charge of the match with a calculated assault from which only Rob Nicol and Chris Martin escaped. Striking 20 fours and three sixes off 137 balls, Guptill put Auckland in sight of victory through useful stands with Richard Jones, Ravi Bopara and Styris, before falling for 156.
While Guptill's effort scuppered Canterbury's chances, Central Districts faced no such problems from Otago, easing to a 59-run victory in Dunedin. The toss was one of the few things that went right for Otago, who were immediately on the back foot with Central Districts' rapid start to the innings. Neil Wagner and Yasir Arafat engineered a strong comeback, getting three wickets for seven runs to stifle the momentum. However, their joy was short-lived as Timothy Weston and Jacob Oram rebuilt the innings with a 121-run stand that set Central Districts up for a strong finish. While both batsmen missed hundreds, the lower middle-order ensured that their work did not go to waste as Kieran Noema-Barnett, Graham Napier and George Worker pushed Central Districts to 297 before a late spark from Ian Butler bowled them out in the last over. Despite getting starts, none of the Otago batsmen were able to play the anchor role and they floundered to 125 for 5 just after the halfway mark. Butler was again in the thick of action, trying to spark a lower order revival, but steady spells by Central Districts' back-up bowlers ensured that the script ended in their favour. Oram picked up 3 for 48 as Otago's innings folded in the 45th over.
Wellington completed a 22-run win against Northern Districts in a rain-affected encounter at Seddon Park. Kane Williamson's 70 was the mainstay of Northern District's innings, while Michael Parlane and Anton Devcich chipped in with useful contributions. Dewayne Bowden, Andy McKay and Paul Hitchcock took two wickets apiece to keep the score down to 223. Wellington's chase looked to be on course when the heavens opened in the 35th over of the chase with the score on 156 for 4. Mathew Bell's responsible 40 had taken charge of the chase when the D/L method adjudged Wellington the victor.
