Police Powers and Responsibilities Act 2000

If a police officer excludes a person from being present during questioning, the police officer must—

if the excluded person was a friend, relative or lawyer—advise the relevant person that the person may telephone or speak to another friend, relative or lawyer, to ask the person to be present during the questioning; and

if the relevant person arranges for another person to be present—delay the questioning for a reasonable time to allow the other person to be present during the questioning.

Also, the police officer must arrange for someone else to be present during the questioning if—

the police officer must not question the relevant person without a support person being present because of a requirement under this Act; and

the relevant person has not arranged for another person to be present during the questioning.
