MOSCOW - New Zealand opened a big head in the first half and cruised to a 31-12 win over Canada on the opening day of the World Cup Sevens rugby tournament.
New Zealand was up 19-0 at the half and went on to win on two tries from Sherwin Stowers and a try each from Kurt Baker, Pita Akhi and Gilles Kaka, who added three conversions.
Harry Jones and Nanyak Dala had tried for Canada. Team captain Nathan Hirayama converted Dala's try.
New Zealand, the dominant team in the annual world series but winner of its only World Cup 12 years ago, opened the scoring quickly. Baker scored a try 1:27 into the game, and Kaka's convert gave the Kiwis a 7-0 lead.
New Zealand went up 14-0 when Kaka converted Akhi's try at 3:42 of the first half. Stowers added an unconverted try less than two minutes later, and New Zealand went into halftime with a 19-0 lead.
Canada got on the board just 42 seconds after the break as Jones's try cut the lead to 19-5. But Stowers restored New Zealand's lead with his second try of the match at 2:21 of the half.
Dala's try and Hirayama's conversion narrowed the lead to 24-12 and gave Canada life, but with time running out Kaka converted his own try to put the game away for the favourites.
Every team made a single appearance before a sparse crowd at Moscow's Luzhniki Stadium, the 1980 Olympic venue, with the pool games to be completed on Saturday before the playoffs on Sunday.
