New Zealand’s T20I series against West Indies starting on Friday should be a springboard for the home side to look to improve their results and build a squad for next year’s World Cup, former captain Brendon McCullum said.

New Zealand are second in the ICC Test rankings and third in one-day internationals, but struggling at sixth in the T20Is. The team lost their last two series at home and have won just seven of their last 20 matches in the shortest form of the game.

McCullum, however, blamed the inconsistent results on the team’s efforts to succeed in the longer formats, using Twenty20 as a chance to develop new players or give veterans a rest.
