2022 Chatham Islands mayoral election

Croon successfully ran for re-election. Although the election was officially non-partisan, it was analysed within the wider context of polarised public opinion regarding the Sixth Labour Government's Three Waters reform programme. Croon was one of three elected mayors to strongly support Three Waters (in contrast, 6 mayors gave it soft support, 14 were on the fence, 30 gave it soft opposition and 13 gave it strong opposition). After her election victory, Croon gave an interview on Te Ao Māori News.
