With TVNZ's Mastermind set to debut this weekend, host Peter Williams gave viewers a taste of the show, putting his fellow Breakfast colleagues to the test.
But in a surprising twist, it was weatherman Sam Wallace that took the top spot in the show's Mastermind chair.
Tasked with five questions each on a specialist subject of their choice, Wallace chose 'Cars and engines', from which he scored three out of five points.

Despite the hosts' best efforts, both Nadine Chalmers-Ross and Rawdon Christie were outmaneuvered by their weatherman's superior knowledge.
