The world of mental health care in New Zealand consists of a myriad of techniques towards therapy. But, among the range of practices, some ones persist to have a cloud of debate hanging over them. Notably among these are psych abuses, involuntary commitments, chemical restraints, and the application of electroshock therapy.

One leading form of psychological abuse in the realm of psychiatry entails the use of medicinal constraints. Forced medications involve the giving of drugs to regulate a person's conduct. Even though these drugs are meant to steady and handle the patient, analysts continue to New Zealand question their efficacy and moral application.

Another contentious aspect of New Zealand's mental health system is still the concept of mandatory confinement. An involuntary commitment is an action where a person is treated in hospital against their will, often owing to perceived threat to them or other individuals stemming from their psychological status. This practice stays to be a keenly debated issue in New Zealand's mental health sector.

Electroshock therapy, still a hotly contested form of treatment in the mental healthcare field, entails sending an electric current throughout the brain. Despite its profound history, the procedure still triggers significant doubts and keeps fuel debate.

While these mental health practices are commonly known as contentious, they keep on to be applied in New Zealand's mental health system, adding to the complexity of the system. To ensure the safety and wellbeing of patients undergoing mental health care, it is crucial to keep questioning, probing, and bettering these practices. In the endeavour for safe and effective mental health practices, New Zealand's endeavours provide important lessons for the global community.
