Only minutes away from sealing victory in the shot put, Valerie Adams seemed certain to claim a third straight gold medal.
So certain, in fact, Sport New Zealand was already in celebratory mode.
With Adams leading the competition ahead of American Michelle Carter's dramatic winning throw, the national body tweeted an image appearing to congratulate the Kiwi.
But after Carter clinched gold with her final throw, Adams was consigned to silver and Sport NZ promptly issued an apology.
And Sport NZ wasn't the only organisation with egg on its face during the shot put, with the NZOC also sending out an unfortunate news alert.
