The biggest upset of the day came as the newcomer, Damiani Italia Challenge, steered by Francesco Bruni convincingly put away undefeated Emirates Team New Zealand in the best tacking duel seen in this series after winning the start.
The ten international teams were racing in the first of five day's competition in the second round of the match race regatta on Auckland Harbour. After a long wait for a northerly breeze to fill in they raced in conditions that ranged from ten knots for the first of five races to 18 knots by the end of the day.
China skipper Ian Williams narrowly held off Shosholoza's Paolo Cian until the start of the second run when the South African boat had gennaker problems that saw them trawling the big chute like a giant drogue.
There were two other races. Cup champion Russell Coutts dished out a master class on starting technique in his matchup with Italy's Luna Rossa sailed by Peter Holmberg. The Americans won by 58 seconds.
There was a closer race between Gavin Brady steering the Greek Challenge and the French boat Pataugas K-Challenge with Sebastian Col at the helm. The French prevailed all around the course.
