Are Judge Only Mental Health Act Hearings Legally Required to Be Audio Recorded?

I’m hoping someone with experience in NZ law or mental health proceedings can help clarify something.

When a judge-alone hearing is held under the Mental Health (Compulsory Assessment and Treatment) Act, specifically for a Section 16 review/request, is there a legal requirement for the hearing to be audio recorded?

If so: • Which legislation, regulation, or court rule sets out this requirement? • Is the recording automatically kept on file, and can the patient (or their representative) request a transcript? • Are there any circumstances where a Section 16 hearing would not be recorded?

Any guidance, official references, or experience from lawyers, advocates, or people who’ve been through the process would be appreciated.

Thank you!
