Mental Health provides an analysis of the interaction between the mental health system and the law in New Zealand. It provides extensive commentary and discussion on mental health law and practice and provides clear practical guidance on and understanding of complex clinical realities that arise in this area of legal and medical practice. The content is taken from Sylvia Bell and Warren Brookbanks Mental Health Law in New Zealand (3rd ed, Thomson Reuters, Wellington, 2017). Since the previous edition, the book has been restructured and includes new content on social media and young people, the committal process and mental health advocacy.
