Who may legally require you to give a blood sample?

The other crash party or an ambulance officer
According to New Zealand traffic regulations, police officers, doctors, or specially authorized personnel have the right to request blood samples from drivers. This is because they possess the expertise and legal authority to accurately determine whether a blood test is necessary to confirm if the driver is under the influence of alcohol or drugs, thereby ensuring road safety.
