In 2007, the year before the last Olympics, nine finished in the top three of their respective world championships but this number jumped to 17 in 2010 and 21 last year - 22 if the women's hockey team are included after they finished third at last year's Champions Trophy. This won't translate into 22 medals in London because the level of competition is always higher in Olympic year.
Valerie Adams (shot put) and Hamish Bond and Eric Murray (rowing) are strong favourites for gold in London with Lisa Carrington (canoeing), Mahe Drysdale (rowing), Andrea Hewitt (triathlon), Jo Aleh and Olivia Powrie (sailing), Rebecca Scown and Juliette Haigh (rowing), Storm Uru and Peter Taylor (rowing), Nathan Cohen and Joseph Sullivan (rowing) and Linda Villumsen (road cycling) also contenders.
