New Zealand has won the World Rugby Sevens Series a record 12 times. No other county has won more than twice. New Zealand were particularly dominant in the early years of the Series, winning the first six series.

The team has won twelve of the fifteen IRB Sevens World Series events. Since 2000 when the series first started, the only times they have not won the series were in 2006 when Fiji were crowned champions, 2009 won by South Africa, 2010 when they came second to Samoa and 2015 when Fiji won the series. The team has won 47 tournaments out of 122 held.
In the 2006–07 series, it was left until the last round at Murrayfield, Edinburgh, to find out who would win. If Fiji had won their quarter-final against Wales then they would have won the series but they lost 21–14. This meant that New Zealand needed to win the final against Samoa to win the title. With a convincing six tries to one, 34–5 scoreline, they did just that and were crowned champions.
The 2007–08 series saw New Zealand set several records. They became the first team in the nine-year history of the IRB Sevens to have won the first four events of a season, having won the Dubai, South Africa, Wellington and USA tournaments. During the USA Sevens, they broke their own record, set in 2001 and 2002, for most consecutive match wins in the IRB Sevens. The team extended their streak of tournaments won to the first five of the season, and a record seven overall, by defeating South Africa in the final of the 2008 Hong Kong Sevens.
Their record streaks of tournaments won (7) and match wins (47) ended in the final of the Adelaide Sevens with a 15–7 defeat to South Africa. Although they would lose to England in the Cup quarterfinals of the next event, the London Sevens, they won the second-level Plate final, giving them enough points to secure the 2007–08 series crown with one round to spare.
