HAMILTON (Reuters) - Nathan McCullum took four wickets, including two in two balls, as New Zealand beat Pakistan by 39 runs and wrapped up Twenty20 series 2-0 in their second match at Seddon Park on Tuesday. Off-spinner McCullum, principally bowling around the wicket, cleverly varied his pace, flight and angles to bamboozle the Pakistani batsmen, and finished with figures of 4-16 off his four overs and the man of the match award. Pakistan opener Hafeez had looked set to anchor the visitors' run chase of 186 for victory, racing through to 46 before Umar Akmal called him through for a second run, stopped mid-pitch, and left the 30-year-old stranded and glaring back at the youngster as Peter McGlashan removed the bails. Hafeez's dismissal came just one ball after Ahmed Shehzad had been well caught in the deep by Scott Styris for 15 after the pair had combined for a 44-run second wicket partnership and seemingly set to provide a launch pad for their batters. New Zealand opener Martin Guptill followed up his 54 in the first match on Sunday with 44 and shared in a 91-run second wicket partnership with James Franklin (40), while Scott Styris smashed a blistering 34 from 14 balls. Wicketkeeper McGlashan (26) provided some late excitement with his innovative batting producing 24 runs, including two reverse slaps for six, from the first five deliveries in the 18th over by Umar Gul, who bowled a bouncer on the final ball to concede only a bye. Captain Ross Taylor finished 30 not out while off-spinner Saeed Ajmal finished with 3-35, which included two wickets in New Zealand's final over. New Zealand won the first game in Auckland by five wickets, with the final match in the series scheduled for Thursday in Christchurch. Pakistan made one change, bringing in Asad Shafiq for Fawad Alam. New Zealand, rotating their players, fielded Ian Butler and gave Wellington's Luke Woodcock his first international cap in place of Adam Milne and Dean Brownlie who debuted in Auckland. The match got off to a comical start when the ball slipped out of Pakistan opening bowler Abdul Razzaq's hand and dropped a few metres up the pitch before it was called a dead ball. But Razzaq had the last laugh. His first official delivery enticed Jesse Ryder into a swipe only to have the leg-side ball tip off his glove into wicketkeeper Umar Akmal's hands, the opener departing without troubling the scorers. Saeed Ajmal was the best of the Pakistan bowlers taking three for 35 off four overs with strike bowlers Shoaib Akhtar, one for 42 and Gul, none for 47 feeling the heat from the New Zealand batsman. Pakistan got off to a promising start with opener M Hafeez hitting 46 from 30 balls.
