Kiwi sailors Paul Snow-Hansen and Dan Willcox have finished fourth in the medal race at the 470 world championships in Greece but there is no change to their overall finish of ninth.
In medal contention with two days remaining, the New Zealanders plunged from fourth to ninth in the penultimate session at Thessaloniki.
Last year's silver medallists had no chance of reaching the podium in the double points medal race which was won by Mat Belcher and Will Ryan, handing the Australians the title.
It was the first international regatta for Snow-Hansen and Willcox since their 10th placing at the Rio Olympics.
They have committed to pursuing another Olympic campaign at Tokyo in 2020.
There were no Kiwis in the women's fleet following the retirement of Polly Powrie and a year's break taken by her former world champion-winning crewmate Jo Aleh.
