Babe said Still, who is a student at Whangarei Girls' High School, ran a well-executed tactical race in windy conditions, kicking away strongly from the leaders as she opened a gap of 30m between her and the 25-strong field.
Earlier this month, Still's fellow Athletics Whangarei member Corrine Smith was the outright winner of the mixed 3km walk at Athletics Auckland Hot Meet in Waitakere.
The 46-year-old Smith clocked a time of 15 minutes and one second to sit third in the national rankings.
At the same competition, Still was a comfortable winner of her 800m race and Ella Harold, 13, made her debut in senior competition, winning the under-15 in the combined women's 3000m race.
Late in January, Smith easily cleaned up the competition in the bathtub race at the Pahi Regatta, winning by a good margin from the otherwise all-male field.
