The Piri Weepu-led Blues survived an overtime thriller in the final against the Brumbies to win the inaugural World Club 10s rugby tournament in Singapore on Sunday night.
The Auckland-based side pipped their Super Rugby rivals from Canberra at the post in the final, prevailing 10-5.
The Blues were led by World Cup-winning former All Black halfback Weepu, and did well to scramble from behind in the final after conceding a try to the Brumbies' Conrad Hoffmann in the sixth minute.
Forward Tom McCartney got the Blues back on terms in the second-half of the 20-minute finale, before midfielder Jackson Willison secured the winner in golden-point extra-time.
The Blues attended the event as part of their workload over Super Rugby's June hiatus, and would have been rapt to secure the inaugural title. They resume the competition this weekend with a must-win trip to the Force in Perth.
The tournament included eight professional teams and was the first major event to be held at the state-of-the-art new Singapore National Stadium, which is the centrepiece of a $1 billion Sports Hub complex.
The Tana Umaga-coached Asia-Pacific Dragons beat the Cardiff Blues to clinch third place. The Dragons are being mooted as a Singapore-based potential entry in the expanded Super Rugby competition.
Almost 11 000 people attended the two-day event at the stadium which features a domed, retractable roof and air-cooled seating.
