A maiden half century from James Vince powered England to a convincing seven-wicket victory over New Zealand in the opening Twenty20 international in Christchurch on Friday. Vince top-scored for the tourists with 59 as England chased down New Zealand's 154-run target in 18.3 overs to take a 1-0 lead in the five-match series. While Vince's man-of-the-match performance caught the eye, captain Eoin Morgan was also full of praise for his bowlers, who laid the platform for victory by restricting the Black Caps to 153 for five. "The game was won and lost in the first innings... James Vince played outstanding well but all credit to the bowlers today," he said. A three-wicket haul from spinner Mitchell Santner was not enough to rescue the Black Caps, whose batting line-up failed to fire after Morgan won the toss and sent them in. England's win came despite the absence of several senior players, who have been rested for the series after a grueling period that saw them win the World Cup and fail to reclaim the Ashes. A trio of debutants in the team facing New Zealand fitted in seamlessly, with Sam Curran and Pat Brown both snaring a wicket each. All-rounder Lewis Gregory was not needed with either bat or ball and will hope to make an impression when hostilities resume in Wellington on Sunday. Morgan said his squad was building its depth by blooding youngsters ahead of the T20 World Cup in Australia next year. "It's a chance for them to stake their claim," said the England captain, who emphatically ended the match with a six off the final ball to finish on 34 not out. New Zealand's regular captain Kane Williamson is out of the series with a hip injury and the Black Caps sorely missed his batting prowess. Stand-in skipper Tim Southee said there was room for improvement in bowling, batting and fielding. "We were probably a little bit off in all three areas," he said. "We got a score on the board that we felt we could defend but we were a little bit off with the ball and in the field, which didn't help." The poor form that dogged Martin Guptill at the World Cup continued when Curran coaxed an inside edge that crashed into middle stump. Fellow opener Colin Munro tried to break the shackles but was too aggressive against Chris Jordan and was caught on the boundary for 21. In reply, Jonny Bairstow made a positive start for England and it took a spectacular catch from Guptill for dismiss him for 35. Santner and fellow spinner Ish Sodhi had some success pegging back England's run rate before Vince and Morgan combined for a 54-run partnership that proved decisive. It is the first time the sides have met since the one-day World Cup final in July, which ended with scores tied but England claiming victory because they had scored more boundaries. However, both teams insist their focus for the series is on preparing for next year's T20 World Cup. England are ranked second in the world in T20s behind Pakistan, while New Zealand are sixth. Williamson's bowling action given the all-clear New Zealand captain Kane Williamson's bowling action was given the all-clear Friday after he was reported during the first Test against Sri Lanka in August. The right-handed batsman and occasional off-spinner came under scrutiny in Galle during a Test that Sri Lanka won by six wickets. He subsequently underwent a bowling assessment in England last month, where his action met the elbow extension angle permitted under ICC rules. "The International cricket Council today confirmed that the bowling action of New Zealand captain Kane Williamson has been found to be legal, and he can continue bowling in international cricket," the ICC said in a statement. Williamson is not playing in the ongoing home Twenty20 series against England after a recurring hip injury flared up. England won the opening game on Friday by seven wickets.
