Returns of donations and expenses for all candidates (except 2 unsuccessful) are on the council website here (scroll about half way down), all are pdf copies.
The biggest spending was by the mayoral candidates, as might be expected. They were topped by that of Janet Holborow who declares $19,543 (the return is reproduced below) then followed by Rob McCann at $16,150 and Mr Mitchell third at $15,168.
There was a big variation overall in spending from a reasonable amount to nothing. Candidates for the Paekakariki Board didn’t need to campaign, a few others elsewhere managed to get elected on the basis of name recognition alone. Donations declared were sparce.
