Triumphant New Zealand arrive from Beijing today having proved they are still the team to beat in the IRB World Sevens Series. The Kiwis overwhelmed South Africa in the Cup final at the Beijing Sevens and reminded all pretenders that they will not easily relinquish their crown at this weekend's Credit Suisse First Boston Hong Kong Sevens. New Zealand, led by the inspirational Eric Rush, defeated South Africa 41-14 yesterday to win the sixth leg of the IRB series. They underlined their dominance by knocking out Fiji 35-12 in the semi-finals and crushing the United States 40-7 in the quarter-finals. Hong Kong, meanwhile, ended in the Shield competition where they lost 40-5 to Japan in the final. The SAR were knocked out of the Bowl competition early in the day, losing 36-5 to France before registering their first victory in the tournament, a 29-7 win over hosts China in the Shield semis. 'We gradually got better as we went along. But we have a lot to do before we can close the gap against the better sides,' coach Craig Pain said. Pain said the 12-strong squad, led by Chris Gordon, remained injury free and there were unlikely to be any changes for this weekend's tournament. 'We will have to sit down and evaluate our performance. But I don't think there will be any changes unless they are forced on us.' Gordon Tietjens' Kiwis increased their lead over second-placed South Africa in the IRB series to 12 points with their victory in Beijing. With the halfway mark crossed in this year's series, New Zealand now have 100 points and will be seeking to maintain their stranglehold in Hong Kong. The Hong Kong Sevens, the seventh in the 11-leg series, offers the Cup winners an extra 10 points (30 in all) as it is a 24-team tournament. Fiji were let down by poor defence in the semi-final against New Zealand. Despite flashes of brilliance from legendary Waisale Serevi, the new-look Fijians missed tackles at crucial moments to allow their arch-rivals to canter home. Fiji had earlier beaten England 28-14 in the quarter-finals.
