TV3 picked up the series last year, after TVNZ announced it would not be bringing it back due to falling ratings.
Top chef Josh Emett stayed on as a judge, joined by Al Brown and Mark Wallbank, who replaced Simon Gault and Ray McVinnie.
But despite positive reviews, it seems the culinary cook-off may not be to viewers tastes, with audience numbers dropping by more than 253,000 from last week's Dancing With the Stars final, which screened in the same timeslot.
Meanwhile, TV One saw 626,000 viewers tune in to its current affairs programme Sunday.
