While in San Francisco she spent $6438 on her ministerial credit card on accommodation and transport, including $1242 on a car and driver for one day. The spokesman said Ms Adams attended eight meetings around San Francisco that day including one in San Jose, a return trip of about 160km. As Ms Adams was preparing for the meetings, hiring the car and driver made more sense than a self-drive hire car or taxis.
Maori Affairs Minister Pita Sharples was also in San Francisco for part of the regatta, but no credit-card expenses from him were published yesterday and his office was unable to provide information about the trip's costs.
Foreign Minister Murray McCully stopped over in San Francisco during the racing en route to meetings elsewhere, but his records associated with that trip would be published in the next release, a spokeswoman said.
Labour MP Trevor Mallard also attended the regatta but paid his own airfares, albeit subsidised by the taxpayer, and arranged his own accommodation.
Earthquake Recovery Minister Gerry Brownlee was in San Francisco shortly after the America's Cup ended for meetings with insurance industry experts. He also hired a car and driver for a day, for $1543.
A spokesman said the car was "not a particularly luxurious vehicle" which picked up Mr Brownlee, three others and their luggage from San Francisco Airport before taking them to "valuable" meetings in Oakland and Silicon Valley, then taking them back to the airport that evening.
Social Development Minister Paula Bennett hired a pricey car while in Croatia in July. The car from Thrifty cost $1989 for four days.
"We arrived as Croatia joined the European Union," Ms Bennett said. "Zagreb was packed with ... visitors for the celebrations. Rental cars were scarce and at a premium but Thrifty was the best option."
Mr Joyce's credit-card records show $3116 was spent at Shi Bo De Coffee in Shanghai. A spokesman said one of Mr Joyce's staff had their office ministerial credit card "forcibly taken off them". The card was then used to withdraw money. "The staff member went to police straight away and the money was recovered."
