An issue has come up recently for people trying to get WOF’s – VTNZ insisting that the front brake must operate a rear brake light (as well as the rear brake operating the brake light).
Check section 4-10-2 to see the relevant section:
Mandatory and permitted equipment
1. A motorcycle first registered in New Zealand before 1 January 1978 may be fitted with one or two stop lamps.
2. A motorcycle first registered in New Zealand on or after 1 January 1978 must be fitted with one or two stop lamps.
This would seem to mean that you can just have one brake light, i.e. operated by one brake.
