On Saturday, the final day of the tournament, the women's team took third, ahead of the Japanese team, which placed fourth.
Qualifying for the World Junior Curling Championship, Korea took the gold medal, with China placing second.
The coach of the New Zealand Junior Women's Team, Nelson Ede, of Naseby, said the players did well considering they got together as a team three days before the event.
''They [the team] had a couple of opportunities to place a bit higher but the quality of curling was very high.
''One of the things we struggle with is not having enough game time pre-tournament ... it makes it difficult when playing against teams training full time.''
Despite that, the result was a ''good effort'' from a young team and provided good experience for the players, Mr Ede said.
''Taking Japan to a tie breaker - that was a fairly high pressure game for them and they held through to take the win.
''They improved as the tournament went on. Overall [I am] very happy with the way the team performed.''
The men's team could not replicate the third place of the women, finishing fourth in its event, behind Korea, China, and Japan, in first, second and third, respectively.
New Zealand Curling Association media officer Ian Ford said the quality of play and sportsmanship at the competition had been to a ''very high standard''.
''The final was just superb.''
Five teams took part in the event, which began last Monday, playing a double round robin, with the top qualifier advancing directly to the finals.
Players had to be younger than 21 before June 30 last year to be able to participate.
Although the event was first held in 2005, in Japan, this year's competition was the last.
From next year, the event and another, the European Junior Challenge, will be replaced by the new World Junior ''B'' Championships, with the first to be held in Kisakallio, Finland, in January.
