The Safeguard 2019 income survey shows a median base income for full-time respondents (410 of them in the sample) of $96,230, down $3000 from last year.

Respondents were asked which professional body or bodies they belonged to. Of those bodies which were selected by at least 20 full-time respondents, the results were:
IOSH members (32) $115,450
NZISM members (222) $99,270
NZOHNA members (26) $85,830

(As for the discussion title, of course I assume all Forum members are "the best people".)
