The Junior All Whites have been beaten 1-nil by hosts South Korea at the Suwon Under-20 Cup.
The result is New Zealand's second narrow loss to a fellow FIFA U-20 World Cup finalist at the four-nation warm up tournament after losing 1-nil to Uruguay last week.
New Zealand finish the quadrangular tomorrow night against African champions Nigeria who drew 2-all with Uruguay.
New Zealand coach Chris Milicich was disappointed with a second straight loss but thought the experience would serve his team well come the FIFA U-20 World Cup finals in Colombia in July.
