New Zealand sailors Jo Aleh and Polly Powrie are bringing home gold after winning their Olympic sailing regatta in Weymouth.

The pair, who have dubbed themselves team Jolly, say there were focused on treating the regatta like any other event.

They sailed their way into the history books, thwarting the British and winning gold in the women's 470 class.

The win is New Zealand's fourth gold medal at the games. The two Aucklanders are the first Kiwi sailors, who than windsurfers, to win Olympic god since 1984.

BMX

Former Bay of Plenty BMX rider Sarah Walker has added to New Zealand's medal score, winning silver in London.

The 24-year-old had a sluggish first heat of the semi-finals, but recovered to finish second in the medal race – a bike length behind Colombian gold medallist Mariana Pajon.

Walker's friend and training partner, Dutchwoman Laura Smulders, won bronze while three of the competition heavyweights, Australian Caroline Buchanan, Great Britain's Shanaze Read and France's Magalie Pottier all missed the medals.

Team-mate Marc Willers was beside himself after crashing out of his event.

Willers was a medal favourite when he won two of his heats and came second in another.

He was second in his first semi-final before crashing heavily on the final turn.

He tried to come back in the next run, but was unsuccessful and came last.

Canoe

Ohope canoe sprinter Lisa Carrington has qualified for the K1 200m final with an Olympic record.

The 24-year-old and 2011 world champion won her semi-final a metre ahead of Spain's Teresa Potella Rivas in a time of 40.528.

Hungarian rival Natasa Douchev-Janics was the second fastest qualifier, .058 behind the New Zealander.

London 2012 is Carrington's first Games and she has been widely-tipped for a medal.
