How to find someone's current address in New Zealand — lawfully

The question comes up daily in recoveries, litigation support and service of documents: the address on file is old, mail is being returned, and the matter cannot progress until someone establishes where the person now lives. There is no single register in New Zealand that answers it. There is a set of records, each of which holds part of the picture, and a sensible order to work through them.

Start with what you already hold

Before running anything, write down the identifiers on the file: full name and any variants, date of birth or approximate age, last known address and the date it was recorded, any phone number or email address, employer, vehicle details, partner or associate names, and any company association. Each of those is weak alone. Together they let you reject a wrong match quickly, which is the part of the job that actually saves money.

Pay particular attention to the date attached to the last known address. An address recorded eight months ago in a credit application behaves very differently from one taken off a contract signed in 2019, and it changes which source is worth querying first.

The records that hold an address

Credit file address history

Credit reporting data held by Equifax and Centrix is usually the most current address source in the country, because it refreshes whenever the subject applies for credit, finance or a utility account. It is also the most tightly controlled. Access is conditional on the Credit Reporting Privacy Code 2020 and on the credit reporter's own contract, both of which limit who may search and for what. Every access is logged by the credit reporter, so a search run outside a permitted purpose is discoverable after the fact.

Company and director records

If the subject has ever been a director or shareholder, the Companies Register gives a service address, an address for the company, and a set of related entities that often produce further addresses. Recent director privacy changes have reduced what is shown, but the entity links remain, and they are frequently the fastest route to a current position.

Property and title records

LINZ title records tie a name to a legal description and, through sales history, to a timeline. Ownership does not prove occupancy — plenty of people own a rental and live elsewhere — but a title match is a strong identity anchor and often corroborates an address obtained from another source.

PPSR and insolvency

Registered security interests on the PPSR and entries in the insolvency registers both carry address information supplied at registration, and both tell you something about the subject's circumstances at a known date. For recovery work this doubles as a viability signal.

Digital footprint

Phone numbers, usernames, email addresses and publicly visible social media signals resolve to linked accounts and platform registrations. This rarely produces an address directly. It produces a contact point, and a contact point is often what actually moves the file when a postal address is stale.

The order that finds an address fastest

Work outward from the strongest identifier rather than running everything at once. If there is a company association, start there — it is cheap, public, and yields related entities. If there is property, take the title next. If neither applies, credit file address history and directory data carry the enquiry, with digital footprint tracing used to establish a live contact point. On intelID these run together against one query, which removes the sequencing problem but not the judgement: you still have to read the dates.

Corroborate before you act

The single most useful habit in address work is refusing to report on one source. Two independent records agreeing on the same address, ideally recorded at different times, is the threshold. Record which two agreed. When the address is later challenged — by the subject, by the court, or by your own client after a failed attempt — that note is the whole answer.

The legal limits

Locating a person is lawful where it is done for a lawful purpose connected with your functions, and where the collection is by means that are fair and not unreasonably intrusive. Pretexting — pretending to be the subject, a relative or an official to obtain information — is unlawful collection. Using a database you are entitled to access for a purpose you are not entitled to use it for is a breach even where the search itself was technically available. Passing the address to someone with no lawful interest in it is a disclosure breach.

Safety cases deserve their own rule. Where there is any indication the subject has moved to avoid a person, stop and ask questions before proceeding. The full position is set out in our guide to what the law allows in skip tracing and in the note on authorised purpose under the Privacy Act 2020.

Keep the record as you go

Record, at the time: who instructed the work, the declared purpose, the sources searched, what each returned, which two established the match, and what was reported. Written afterwards, it is a reconstruction. Written at the time, it ends the argument.

intelID requires an authorised-purpose declaration before results are returned and writes an audit record against the user who ran the search. See how tracing runs on the platform, the integrated data sources, or request access.
