Extradition to New Zealand

No Attorney-General Involvement 

One of the important features of this scheme is that the fundamental way in which it differs from Australia’s ordinary extradition process: the core endorsement and arrest process is handled directly by police and prosecuting authorities in both countries, rather than a request being centrally coordinated through the Attorney-General’s Department in Canberra. In Australia’s case, that means the Australian Federal Police and the Commonwealth Director of Public Prosecutions dealing directly with their New Zealand counterparts, rather than the matter passing through the different layers of diplomatic and ministerial oversight that apply to extradition requests involving other countries. 

The one significant exception is where a person sought by New Zealand is already serving an Australian prison sentence, or where seized property needs to be sent to New Zealand as evidence, in these specific circumstances, section 36,37, and 39 give the Attorney-General a direct role. Outside of these particular scenarios, however, the core extradition and warrant-endorsement process itself proceeds without Attorney-General involvement.  

Bail 

When a person is arrested under an endorsed New Zealand warrant, the general position is that they must be remanded in custody, unless special circumstances exist that justify the grant of bail. This underlines the fact that the entire scheme is built for speed and directness, the presumption leans firmly towards detention rather than release while the matter proceeds.  

What Happens After the Hearing 

Where a magistrate orders that, a person be surrendered, the practical work of getting them to New Zealand falls on the Australian Federal Police, who liaise directly with a New Zealand Police Liaison Officer to coordinate the logistics of the handover. Once those arrangements are finalised, New Zealand Police typically escort the person back across the Tasman themselves, at which point the person is handed over to New Zealand authorities to face prosecution in the New Zealand courts.  

When Extradition Must Be Refused 

Despite this streamlined process, an Australian magistrate isn’t simply a rubber stamp for a New Zealand warrant. The Act sets out specific grounds on which extradition to New Zealand must be refused, if the magistrate or an appeal judge reviewing the decision is satisfised of any of the following stated reasons:  

1. The offence is trivial in nature: Extradition exists to deal with genuine criminal wrongdoing, and it is not to be used as a heavy-handed response to minor matters.  
2. The accusation was not made in good faith or in the interests of justice: If there is a genuine question that can be raised regarding the motives behind the New Zealand request, for example if it appears to be pursued for an improper purpose then in that case extradition must be refused. 
3. Substantial amount of delay has occurred since the offence was allegedly committed: Where a delay has occurred to the point that it would be unjust, oppressive or too severe a punishment to surrender the person to New Zealand. The longer the gap is between the alleged offending and the extradition request, the more a court will scrutinize whether surrendering the person would still amount to a fair and proportionate outcome, given how much may have changed in that person’s life in the meantime.  
4. For any other reason, surrender would be unjust, oppressive, or too severe a punishment: This is a broader residual part under section 34(2), distinct from the delay ground mentioned above. It gives the magistrate scope to refuse extradition in circumstances that don’t necessarily involve delay at all, but where surrendering the person would still be unjust, oppressive, or a disproportionately severe outcome in the circumstances, for example, on account of a person’s serious ill health, or some other significant change in circumstances unrelated to the passage of time itself.  

These aren’t matters of discretion for the magistrate, which can be simply weighed up and set aside. If satisfied that any of the above ground applies, then refusal is mandatory and not optional. 

Why The Process Is Different for New Zealand 

The rationale behind this arrangement comes down to the closeness of the legal, political and historical relationship between the two countries. New Zealand extends this same streamlined ‘backed warrants’ approach to only one other country, the United Kingdom, reflecting just how narrow and deliberately selective this kind of arrangement is. Australia and New Zealand share deeply aligned legal systems, comparable standards of criminal justice and a level of mutual trust that is not extended in the same way to countries without that shared history. This is precisely why the backing of warrants system dispenses with some of the procedural safeguards built into ordinary extradition, including the requirement to establish a prima facie case against the person before they can be surrendered, while still preserving the core protections (like the trivial offence, bad faith, and delay grounds) that guard against genuine injustice.
