Emergency Plans Hi Jan. You'll see in the template that Chris sent that Fire and Emergency NZ (FENZ) can review your plan and make suggestions.
If you have Hazardous Chemicals on site (anything with HAZCHEM label son it) above trigger quantities you also need to send a summarised version of your plan to them including site plan, inventories, first responders, access after hours, etc. They have a guide on their website which might help you decide whether you need to go to this extra step:
