But coach Gordon Tietjens said two targets had been set, the World Series was one and the World Cup, to be played in Moscow from June 28-30 was the other. The last round of the World Series is in London next weekend.

"We've had a lot of new players and I am pleased for them," Tietjens said.

"To win with one round to go too is extra pleasing. A lot of credit goe4s to the team, they've committed a lot and it's an awesome feeling.

"We had nine new players in Hong Kong and we are building a depth which is now required on this World Series," he said.

New Zealand beat Argentina 42-10 in their quarter-final while South Africa beat the United States 22-5. New Zealand then beat Wales 26-14 while South Africa headed England 24-17.

South Africa scored first in the final but Lote Raikabula responded almost immediately and the scores were levelled when Tomasi Cama kicked the conversion. Kurt Baker scored just before the half-time break with Cama's conversion seeing New Zealand to a 14-7 lead.

Sherwin Stowers was sin-binned just over a minute into the second half and South Africa scored.

But New Zealand extended their lead moments later when Trinity Spooner-Neera with Gillies Kaka adding the conversion.

However, the traffic was all one way for the remainder as South Africa claimed a 28-21 win.

South African coach Paul Treu said after a season of highs and lows it was good to finish on a high.

"We are almost going to be the only team to win three tournaments up and until now. We had some bad moments, but those bad moments were needed to make up for our results towards the end of the season, and to give credit to our guys, and those back home, for having the faith and belief in the team that we could stay the distance," he said.
