Following National MP Jami-Lee Ross being sectioned to an Auckland mental health unit earlier this week, the Herald looked into the rules around detaining someone against their will.

In New Zealand a person's right to refuse treatment can be overridden under the Mental Health (Compulsory Assessment and Treatment) Act.

Legally, a person may be ordered to have a compulsory psychiatric assessment and treatment if they pose serious danger to the health and safety of themself or someone else, or if they can't take care of themself.

Over 5000 people received a compulsory assessment or treatment in New Zealand in 2016, the latest data available.

Anyone over 18 concerned enough about another person's wellbeing can apply for that person to be assessed.

Each district health board region has a director of area mental health services, who after receiving an application must immediately organise an assessment examination, to be carried out by a clinician.

Police may be required to assist if the patient was still unwilling to co-operate.

There are two periods of compulsory assessment, during which a person's clinician may release them from assessment at any time.

If a preliminary assessment finds reasonable grounds for belief the patient has a mental disorder, they must be assessed and have treatment for up to five days.

After that, the patient could be subject to further assessment and treatment for up to 14 days.

At the end of the second period, if the clinician considers the patient as not fit to be released, an application for a compulsory treatment order must be made to the Court.

The court then determines whether or not the patient is mentally disordered and requires further compulsory treatment.
