Wilson, 16, has competed on the track already, winning the national u18 heptathlon title there last month.
She will compete in the high jump, long jump, javelin and 100m hurdles.
Anderson, 15, a promising cross-country and middle-distance runner, is into the action straight away, with the women’s u18 3000m final starting at 9am tomorrow.
All three athletes are Gisborne Girls’ High School students — Wilson in Year 13, Irving, Year 12, and Anderson, Year 11.
Olympic medallists Tom Walsh (shot put) and Eliza McCartney (pole vault) are among the athletes set to compete in senior competition, although McCartney is under an injury cloud after she pulled out of an event this week with a hamstring niggle.
The athletics track, which opened in October last year, was the opening piece of the $53.65 million first stage of Nga Puna Wai. The extensive complex will replace several facilities damaged in the Christchurch earthquakes.
Irving has a busy itinerary in the next few weeks. She is preparing for the surf lifesaving nationals at Mount Maunganui from March 21 to 24. A week later she will be on the Gold Coast for the Australian surf lifesaving nationals.
Wilson, too, will compete at the New Zealand surf lifesaving nationals at the Mount.
Next month, she will fly to Sydney for the Australian u20 national athletics champs, where she will contest the heptathlon.
