The Great Kiwi Bake Off is a New Zealand television baking competition based on The Great British Bake Off in which 12 amateur bakers compete in a series of baking challenges.^[2] The show's first episode was aired on 16 October 2018 on TVNZ 2. The show is hosted by Hayley Sproull and Madeleine Sami,^[3] with judges Dean Brettschneider and Sue Fleischl.^[4][5] The show, like other spinoffs of The Great British Bake Off, uses a similar style, format, and opening theme song to the British series. Like the British series, the show is followed by a recap special called An Extra Slice, hosted by Chris Parker, discussing the episode of the week and interviewing contestants who have been eliminated.^[5][6]

The programme operates on a weekly elimination process to find the best all-round baker from the contestants who are all amateurs, where in each episode the bakers are tasked with different challenges: a signature bake, a technical bake, and a showstopper. The first season only included two of the three challenges with the exception of the finale. All three challenges were included during the second season. The bakes are critically examined by the judges who will then choose a "Star Baker" and a baker that is eliminated from the competition.

• Signature Challenge: This challenge allows the amateur bakers to show off their tried-and-tested recipes.
• Technical Challenge: This challenge shows who can follow minimal instructions and who also has the technical knowledge and experience to produce a finished product. The bakers are all given the same recipe and are not told the challenge beforehand. The finished product is ranked from worst to best with the judges not knowing who produced which bake.
• Showstopper Challenge: This challenge allows the bakers to show off their skills and talent with the judges looking for a bake with both a professional appearance and great taste.

This season premiered on 16 October 2018 and featured four bakers in the finale instead of the typical three. The season was won by Annabel Coulter from Timaru. Runners-up were Stacey Johnsen, Jeff Poole and Hannah Ward.
