Peter Taylor and Storm Uru have scored New Zealand's seventh medal of the Olympics, with bronze in the men's lightweight double sculls.
Denmark won the dramatic final, coming through the British defending champions in the final 100 metres in the tightest clash of the Olympic regatta.
Britain had powered off the start and led for 1,900 metres by half a length but they could not hold off the Danish boat of Mads Rasmussen and Rasmus Quist who sprinted for the line.
Denmark finished with a time of 6:37.17, claiming Denmark's first gold medal of the games. Britain finished in 6:37.78 and New Zealand came in three seconds later with a time of 6:40.86.
The race had to be restarted after the British boat broke their equipment in the first 100 metres, prompting the officials to restart it 10 minutes later.
Zac Purchase, the defending champion, lifted his seat into the air to show his equipment was broken, prompting the race umpire to halt the final. The other crews then returned to the start.
British coaches were then seen trying to fix the seat with a screwdriver.
Meanwhile, New Zealand's Emma Twigg had a good race in the single sculls final, finishing fourth in a strong field.
She came home in 8:01.76, around seven seconds behind the winner Miroslava Knapkova from the Czech Republic.
Knapkova powered to victory adding to her 2011 world championship title and finally confirmed her position at the top of the sport.
The 31-year-old, who had previously won a string of silver and bronze medals at international regattas, had a strong start and led by over a length by 500 metres and established more than a boat's length of clear water before 1,000 metres in one of the most dominant finals of the regatta.
Denmark's unheralded Fie Udby Erichsen took silver and Australia's Kim Crow the bronze.
