The celebrity chef judges - Karena and Casey Bird, Cameron Petley and Rex Morgan - were "blown away by the calibre of contestants" this season, Ms Rogers said.
A highlight was travelling around the country experiencing the hospitality of each marae and judging kai unique to each area, she said.
"We loved it - the flip side was that it made it a lot harder to eliminate teams. As judges, we really struggled with that."
Producer Kay Ellmers said the series was about celebrating the efforts of those keeping marae functioning.
"We get to see the determination, skill, grace and humility they bring to the table; at home and in the competition."
