The All Blacks Sevens bounced back from their Wellington disappoint to record two good wins on the opening day of the American leg of the world series in Las Vegas today.
New Zealand beat France 21-nil and then crunched world champions Wales 40-5 in their opening pool matches.
Belgium Tuatagaloa starred with two tries in the comfortable win over France.
Ben Lam was the hero against Wales, notching a hat-trick of tries with youngster Rocky Khan also dotting down.
Short on experience after a string of injuries, Gordon Tietjens' side looked slick today and should be able to get past Argentina in their final pool match tomorrow before the quarterfinals.
Fiji, South Africa and defending champions Samoa were the other unbeaten teams on the opening day to lead their respective pools.
The big shock was the sudden demise of England who were impressive in winning the Wellington title last weekend.
They were beaten 26-17 by Fiji, then they were thumped 21-5 by Portugal in a major upset.
