Emirates Team New Zealand drew first blood on day one of the 35th America's Cup, recording back-to-back victories over Oracle Team USA on Saturday.
In a rematch of the 2013 final - when the US crew sensationally overturned an 8-1 deficit to triumph 9-8 - New Zealand began with a one-point disadvantage due to their rivals winning the preceding qualifying regatta.
Peter Burling's team quickly got back on level terms as the US - helmed by Jimmy Spithill - failed to recover from an early penalty in race one for crossing the start line too early.
In race two, New Zealand's early advantage was reduced on the run to the fifth mark.
However, the US yacht then hit trouble and Burling was able to guide New Zealand to a comfortable victory by a minute and 27 seconds.
The final is a race to seven points, with New Zealand now 1-0 ahead of two races on Sunday.
