Summary Offences Act 1981, s s 3, 4(1)(a) Case: Morse v Police [2011] NZSC 45 

Protestors are sometimes charged with behaving in an offensive or disorderly manner in a public place. This is a minor criminal offence, punishable by a fine of up to $1,000. However, the police can still arrest you without a warrant for this.

To get a conviction, the police would have to prove something more than, for example, that some people were seriously offended – they’d have to prove you disrupted public order so that other members of the public weren’t able to go about their normal activities in that public place.

There’s also a more serious version of this offence, which is where your behaviour is likely to cause violence against people or damage to property. This carries the possibility of a short jail term, up to three months, or a fine up to $2,000.

Summary Offences Act 1981, s 4 

Offensive language in a public place is a minor criminal offence in New Zealand. In some cases, repeatedly swearing on a protest could result in a conviction for this offence.

However, this will depend a lot on the particular circumstances, including exactly what you said, how often, and so on. The judge will take into account your right to freedom of expression under the Bill of Rights in deciding whether on balance how you behaved was serious enough to breach the criminal law.

In some cases, swearing at the police on a protest could also amount to “offensive language”. However, the courts have said that police officers (along with other professionals who deal with vulnerable people like WINZ staff, teachers, nurses, and doctors), should be expected to put up with a greater amount of abuse than ordinary members of the public. The judge will take this into account in deciding whether on balance your behaviour amounted to “offensive behaviour”.

Threatening a police officer could amount to the offence of assaulting a police officer, which is punishable by up to six months’ jail or a fine of up to $4,000. This is because an “assault” includes the threat of an assault.

There are restrictions around when and where you can make noise. Your local council is responsible for deciding whether the noise is above a reasonable level. If a council noise control officer thinks you’re making too much noise at a protest, they could issue you an Excessive Noise Direction (END), ordering you to reduce the noise to a reasonable level. If you don’t immediately obey, the police can take away things that you’re using to make noise – for example, drums or a megaphone (see: “Noise”).

Summary Offences Act 1981, s 11

You could be charged with wilful damage if you intentionally damage property.

If you damage property accidently, you might also be responsible under the civil (non-criminal) law for paying for the damage.

Glitter bombs, shoes, tomato juice, and many other items have all been thrown in the name of different causes. Throwing things, even soft things, may legally be a criminal assault.

Crimes Act 1961, s 86

Yes. There is no New Zealand law that explicitly prohibits you from disguising yourself during a protest.

It is possible that a disguise can be taken as indicating that you intend to do something illegal. However, being disguised on its own doesn’t turn a peaceful assembly into an unlawful one.

Dog Control Act 1996

Yes, but you may need to obey laws to do with things like leashes, registration, and dangerous dogs. There will be bylaws set by your local council that you can check. If you bring an animal, you can be held responsible for its actions.
