Investigations and compliance

Immigration compliance and investigations play a vital role in ensuring the integrity of the immigration system is maintained and immigration harm is minimised.

Our investigations and compliance teams investigate immigration offending, ensure employers comply with immigration law, ensure migrants comply with the conditions of their visas and are in New Zealand lawfully.

This includes managing breaches and investigating offences against the Immigration Act 2009. Breaches or offences range from residing in New Zealand unlawfully, employing a migrant outside of the conditions of their visa, providing false information on a visa application, or trafficking in persons. A breach or offence could result in deportation from New Zealand or criminal charges being laid.

Demand for immigration compliance activity has grown. Since the border fully reopened in July 2022, we have seen more evidence of immigration non‑compliance as a result of strengthened compliance requirements (including under the Accredited Employer Scheme), maximum continuous stay periods for lower skilled AEWV holders, an increase in asylum cases requiring compliance activity and an increase in awareness and reporting of issues.

3 new teams will be established in 2026 to respond to serious offending, protect people from harm and exploitation, and increase the number of cases investigated - strengthening our response to migrant exploitation and immigration non-compliance.

These include: 

• Another Immigration Investigations team, targeted at reducing complex case backlogs and responding to serious immigration offending.
• An additional Labour Inspectorate team, expanding capacity to detect and respond to migrant exploitation and serious breaches of employment standards. 
• A new Immigration Compliance team, focused on addressing lower‑level employer non‑compliance and people in New Zealand unlawfully or in breach of their visa conditions.

Managing reports of an immigration breach or offence

All reports are taken seriously. They are treated with confidence and can be made anonymously.

When a report is made about a possible immigration breach or offence, an assessment is made to determine the veracity and severity of the allegation and how it is best addressed. All reports receive a response proportional to the issue, which means not all reports will be referred to an Investigator or Compliance Officer. A report will be referred to the team best placed to address the issue, whether that be the investigations team, compliance team, the most appropriate team within Immigration New Zealand (INZ), wider MBIE (such as the Labour Inspectorate) or other agencies.

Investigations

Our investigations team investigate complaints of immigration offending. They focus on the most serious criminal offending such as people trafficking, migrant exploitation and transnational organised crime.

Our investigation teams operate in the criminal jurisdiction and if they decide to pursue a prosecution they are required to reach the criminal burden of proof, that being beyond reasonable doubt for any prosecution.

Due to the nature of this offending, and the high threshold for criminal investigations, immigration investigations can be complex and take time to complete.

But not all allegations considered by an Investigator will lead to a prosecution. Investigators consider a number of options available to them when conducting an investigation, depending on the severity of the offending. These include:

• criminal prosecutions
• issuing infringements 
• issuing formal warnings
• educating people on the right thing to do
• referring to other regulatory bodies as appropriate.

Last financial year (1 July 2025 to 30 June 2026), our investigations team received 1,538 complaints. We completed 454 immigration investigations. Each investigation may result in multiple actions taken.

Of the investigations in 2025/26 financial year (1 July 2025 to 30 June 2026), there were 454 investigation actions taken, including prosecuting 25 individuals. 1,915 complaints resulted in outcomes other than a formal investigation. If no sufficient evidence of criminal offending is found, the investigation will be closed.

The figures below represent the raising of one allegation as a case for Investigations to consider.

One Investigation does not always have only 1 outcome. The following information covers all individual actions taken by an Investigator from the total Investigations completed. This reflects that 1 case can have multiple defendants and victims.

Compliance

People coming to New Zealand need to have a valid visa and comply with their visa conditions.

Compliance officers engage with individuals who may be unlawfully in New Zealand without a visa or in breach of their visa conditions. They assess the severity of the case and prioritise cases where there is higher risk of immigration harm.

Not every case will result in a deportation order or deportation liability notice. Our approach is tailored based on each migrant’s personal circumstance to address situations effectively and promote compliance.   

People who are in New Zealand after their visa expires will receive a letter telling them they must leave the country if they do not have a valid visa. We monitor these cases and individuals are encouraged to leave the country voluntarily or, if they can, get a new visa to remain here lawfully, in the first instance.

Options include:

• working with people to voluntarily depart New Zealand
• deporting people from New Zealand
• making people liable for deportation
• issuing employers with infringement notices
• work with individuals to regularise their immigration status so they can remain here lawfully
• informing and educating people — providing accessible information and making it easy for people to do the right thing.
  
  Last financial year (1 July 2025 to 30 June 2026) our compliance team received 5,961 complaints. As a result, we issued 635 deportation orders, 524 deportation liability notices and 167 infringements under the infringement scheme.

*Note: Infringements are issued by both Investigations and Compliance.
