At an intersection what do a police officer's directions overrule?

In New Zealand, police instructions take precedence over traffic lights, right-of-way rules, and road signs under any circumstances. This is because police make decisions based on current traffic conditions and emergencies, aiming to ensure traffic safety and smooth flow. In certain situations, such as traffic light malfunctions or at emergency scenes, police instructions can more effectively direct traffic and prevent confusion and potential accidents. Therefore, at intersections, regardless of the presence of traffic lights, right-of-way rules, or road signs, police instructions hold the highest authority, and drivers must comply. This rule reflects a strong emphasis on the safety of individuals and the smoothness of traffic, ensuring that the most suitable decisions can be made quickly in different situations.
