Who has the authority to require you to undergo a breath screening test?

A police officer has the authority to require you to undergo a breath screening test. This power is part of the officer's role in enforcing laws related to driving under the influence. Police officers are trained to identify signs of impairment and are authorized by law to take action when they suspect that a driver may be over the legal limit for alcohol consumption.

This legal authority is in place to ensure road safety and to deter individuals from driving while intoxicated, which can lead to accidents and endanger lives. The other individuals mentioned in the alternatives do not possess the legal power to request a breath screening test; only law enforcement officers have this specific authority under New Zealand law.
