The bill also introduces a new offence of planning or preparation for a terrorist act, and this offence will ensure that making plans for a terrorist act is specifically criminalised in New Zealand. The new offence will give police the opportunity to effectively intervene when the person or a group is planning or making preparations to carry out a terrorist act. The offence will not reach further than is necessary, because it requires proof that the preparatory behaviours were done with the intent to carry out a terrorist act, whether that be a few hours or a few months away. I believe that in order to ensure that this offence enables early intervention, police also need the ability to use warrantless powers of search or surveillance where this is necessary. Terrorist preparations may quickly escalate into a terrorist attack, particularly where a terrorist wants to seize an opportune moment, so police must be able to intervene and stop this from happening.
