Five of the country's leading six triathletes will line up in the third round of the eight-leg world series in Yokohama today.
The only absentee is Andrea Hewitt, who is with her fiance Laurent Vidal as he recovers from a heart attack suffered last month.
Of particular interest will be the performance of Nicky Samuels, the Wanaka-based athlete, who is fighting for redress after being omitted from the team for the Glasgow Commonwealth Games.
Samuels, who is placed 13th on the ITU ranking list, was listed as a reserve for the mixed relay but has appealed the decision. It has taken several weeks for the review panel to make its decision, which is expected in the next few days.
A strong performance from Samuels would not hurt her argument.
