Sham Marriages and NZ Immigration: The Law, the Risks and How INZ Decides

In New Zealand, marrying someone does not get them a visa. That single fact shapes everything about how partnership fraud works here, and how Immigration New Zealand (INZ) fights it. INZ does not grant residence because a couple is married: it grants it because a partnership is genuine and stable, and a marriage certificate is one of the weakest pieces of evidence of that. This guide explains what a sham marriage means in the NZ system, how INZ tests relationships, what the law does to people who fake them, and, just as importantly, how genuine couples who get suspected can prove themselves.

What counts as a sham in New Zealand

New Zealand immigration law recognises partnerships in three forms: marriage, civil union and de facto relationships. All three are assessed the same way. A partnership qualifies only if INZ is satisfied it is:

• Genuine: a real relationship, not an arrangement constructed for immigration purposes
• Stable: likely to endure, with the couple living together in an exclusive relationship entered into intending it to be long term

A sham, in this system, is a relationship, married or not, that fails that test: entered into primarily to obtain an immigration advantage, conducted on paper only, or fabricated entirely, with invented history, rented addresses and scripted stories. Note the asymmetry: a real de facto couple with no certificate at all can qualify, while a legally married couple whose relationship is an immigration arrangement cannot. The marriage itself is rarely unlawful; the fraud is in deceiving INZ about the relationship.

How INZ tests a relationship

Officers assess four broad factors, and they are looking for a coherent life, not paperwork volume:

• Credibility: whether the accounts of both partners, and the documents, hang together. Partners can be interviewed, separately, and inconsistencies in ordinary details (routines, homes, families, finances) are the classic failure point for shams
• How long the couple have been together: a history that predates any immigration motive is powerful; a relationship that begins exactly when a visa problem appears invites scrutiny
• Living arrangements: genuinely sharing a home together, with leases, mail, bills and the traces of a shared household
• Financial interdependence and public recognition: joint accounts and commitments, and a relationship known to family, friends and community, which is where support letters and statutory declarations play their part

INZ can also verify documents with issuers, make unannounced home visits in some cases, and draw on information from other agencies. An arranged story tends to survive the application form and collapse at interview, which is why interviews feature so heavily in partnership decisions. The evidence framework is set out in our Partner of a New Zealander Work Visa guide.

The legal consequences of faking it

• The application: a partnership application based on a relationship INZ finds not genuine and stable is declined, and a visa already granted on false premises can be cancelled
• Criminal liability: providing false or misleading information in an immigration application is an offence under the Immigration Act 2009, punishable by up to 7 years imprisonment, a fine of up to $100,000, or both. Organising sham arrangements for others can also be prosecuted as obtaining by deception under the Crimes Act 1961
• Deportation: a person who obtains residence through a relationship found to be a sham can become liable for deportation, and deportation carries a ban on returning for a set period, up to permanently in serious cases
• Future applications: a history of false information is a character issue that follows the person. Future visas can require character waivers and face deep scepticism, in New Zealand and, through information sharing, in partner countries
• The New Zealand partner: the citizen or resident who lends their name to a sham risks prosecution as a party to the offending, sponsor consequences, and their own credibility with INZ in any future genuine relationship

There is no market price that makes these numbers sensible, which is worth remembering because money is the usual motive on both sides: a fee paid to the NZ partner, or a fee charged by an organiser. Organisers, including unlicensed advisers running relationship schemes, are the enforcement priority, and what happens after a report is covered in our reporting guide.

Coercion is different: when the “sham” is not your choice

Not everyone in a fake relationship is a willing fraudster. Some people are pressured, paid under duress, or trafficked into marriages and relationships used for immigration purposes, and some discover their partner’s motives only later. New Zealand treats exploitation seriously: migrant exploitation can be reported to Employment New Zealand, and protections including the Migrant Exploitation Protection Work Visa exist for workers, while people in immediate danger should contact Police on 111. If you were coerced, get advice from a lawyer, a community law centre or a licensed immigration adviser before INZ contact, not after.

Genuine couple? How suspicion gets answered

Genuine couples do get caught in fraud controls, especially where the relationship is new, long distance, cross cultural, or began around a visa event. What answers suspicion is not outrage but evidence across the four factors:

• A documented history: communications over time, travel together, photos with context and dates, not a folder created last month
• Shared life evidence: joint tenancy, bills, accounts, insurance, wills, shared responsibilities
• Recognition: family and friends who know you as a couple and can say so in their own words
• Consistency: accounts that match across forms, letters, declarations and interviews because they are describing the same real life

If INZ raises concerns, you will usually get the chance to comment on potentially prejudicial information before a decision. Treat that letter as the most important document in the process, answer every point with evidence, and get licensed advice. If the decision goes against you, review and appeal rights and the complaint process are in our guide to complaining to Immigration NZ.

Frequently asked questions

Is a sham marriage itself a crime in New Zealand?

Getting married is not a crime, and NZ has no offence called sham marriage. The offending is the deception practised on INZ: false or misleading information under the Immigration Act 2009, and deception offences under the Crimes Act, plus the immigration consequences of decline, cancellation and deportation.

We married quickly. Does that make our relationship a sham?

No. Speed alone proves nothing either way. INZ assesses the whole picture: history, living arrangements, finances, recognition and credibility. A fast marriage with a well documented genuine life behind and around it can succeed; a long paper trail built around nothing real cannot.

Can INZ interview us separately?

Yes. Separate interviews are a standard credibility tool in partnership cases, and home visits are possible. Genuine couples usually have no difficulty, because ordinary shared life is full of the small consistent details interviews explore.

Someone has offered to pay me to be their partner on an application. What should I do?

Decline, and report it if you can. You would be risking prosecution, a fine of up to $100,000 and prison, plus permanent credibility damage with INZ, in exchange for the fee. Reports can be made anonymously, and our immigration category has more on how reporting works.

My partner visa was declined because INZ did not accept our relationship. What now?

Read the decline reasons carefully: they will identify which factors failed. Depending on the visa type, options include reconsideration, appeal, or a fresh, better evidenced application. Deadlines are short, so get licensed advice immediately.
