Team New Zealand has reacted angrily to news Oracle used illegal boats in the four America's Cup World Series regattas.
Oracle's been stripped of all the titles it won in those regattas after being found to have had a forward kingpost in its AC45 that was heavier than the rules allowed.
Oracle skipper Ben Ainslie claims he never had any knowledge of the modifications.
But Team New Zealand managing director Grant Dalton says they are stunned that that kind of tampering was allowed to happen at the top level of sailing.
Holder Oracle is awaiting the winner of the Louis Vuitton Cup Finals.
Italian syndicate Luna Rossa is one win away from joining Team New Zealand in the America's Cup Challenger Series finals after going 3-nil up over Artemis in the semi-finals this morning.
