I thought it was required by law to have road signs warning of speed cameras operating in the area? There is some indication of cameras operating at the entry and exit points of the SH20 south West tunnel in Auckland, but nothing about speed cameras operating inside the tunnel.

Apparently not anymore, according to the below article it looks like they might have an "anytime anywhere" policy now. https://www.drivingtests.co.nz/resources/where-are-speed-cameras/
