After three medals on day seven, two of which gold, where can New Zealand add to their tally?

Triathlon:
Andrea Hewitt is New Zealand's best chance to medal in the women's triathlon which begins at 8pm. The 30-year-old heads into the event, which also features fellow New Zealanders Kate McIlroy and Nicky Samuels, as the number one ranked triathlete in the world following a consistently strong season. Britain's Helen Jenkins and Australia's Emma Moffatt are also strong contenders for gold on the Hyde Park course.

Rowing:
The last day at Eaton Dorney, can New Zealand finish the regatta in style? Their tally of four medals could be added to with two more finals appearances tonight. Storm Uru and Peter Taylor race in the lightweight double sculls final at 11.10pm. The 2009 world champions posted the second fastest time in the semifinals, behind the British duo of Zac Purchase and Mark Hunter who are the current world champions. Then at 11.30pm Emma Twigg races in the women's single sculls final. The two-time world championship bronze medallist faces are tall order against the likes of Czech Mirka Knapkova, Belarussian Ekaterina Karsten and Australian Kim Crow.

The men's coxless four and the women's lightweight double sculls also race in B finals from 9.30pm.

Cycling track:
The women's pursuit team will need a strong outing tomorrow morning to have a shot at the medals which will be decided just before 5am. They race in the first round against Belarus after 3am where they'll need a time in the top four to ride for the medals.

Tonight Shane Archbold begins the ominium event while Eddie Dawkins takes part in the sprint heats.

Sailing:
Olivia Powrie and Jo Aleh will look to build on a strong first day in the women's 470 from 1.05am while several other New Zealand boats look to secure places in the medal race.

Athletics:
Heptathlete Sarah Cowley returns to the Olympic Stadium for day two of her event but she's well off the pace, sitting in 30th out of 37 competitors.

Meanwhile the 100m heats begin as Usain Bolt makes his first showing at the London Games.

Hockey:
The women's Black Sticks side face a crucial match against the USA at 6am. With four teams tied at the top of group B, New Zealand can't afford to drop one of their remaining two games.

Medal chances?
Uru and Taylor are a real chance for a medal and shouldn't be written off winning New Zealand's fourth gold in rowing at this year's Games. Hewitt and Twigg are considered as 'medal contenders' than 'gold contenders' but on their day could certainly strike gold.
