Bay of Plenty's Callum Gilbert qualified for the semifinal in the third fastest time, before a small slip up on the testing finals course pushed him to eighth overall.
The result was slightly disappointing for Gilbert, but is arguably New Zealand's best result in a slalom kayak following Olympian Mike Dawson's 10th placed finish at the Junior Worlds in Austria 10 years ago.
Gilbert's club mate Alex Hawthorne also had a good event with an overall 18th place finish.
The final day saw C1 take centre stage, with Ben Gibb, who won the Oceania Champs in the under-23 division earlier in the year, sneak into the semifinals on the bubble in 30th place.
A clean, solid performance pushed him up to 21st.
The junior C1 men's team finished fourth in the three-boat teams event, with James Twaite contributing the best individual performance with a 13th place finish.
Jane Nicholas was looking on target for a place in the top 10 of the under-23 C1 women's division before an error at gate 22 of the course dropped her back to 11th place.
Nicholas' disappointment was short-lived however, as teammates and fellow former Tauranga Girls' College students Kelly Travers and Haylee Dangen realised they had won bronze behind teams from Russia and Great Britain.
