Unlike electricians or plumbers, locksmiths in New Zealand are not currently regulated by a government licensing body — meaning there is no single mandatory licence required to work as a locksmith. However, that doesn't mean all locksmiths are equal. Reputable professionals hold recognised industry qualifications, carry proper insurance, and follow best-practice standards. Knowing what to look for helps you hire someone trustworthy and skilled.
Is There a Legal Requirement to Be a Licensed Locksmith in NZ?
At present, there is no statutory licensing regime for locksmiths in New Zealand. This is different from trades like electrical work (regulated by the Electrical Workers Registration Board) or plumbing and gasfitting (regulated by the Plumbers, Gasfitters and Drainlayers Board), where performing restricted work without a licence is illegal.
Because locksmithing is unregulated, anyone can technically call themselves a locksmith. This makes it especially important for homeowners to do their homework before handing over access to their property.
Industry Qualifications and Certifications to Look For
While there is no government-issued locksmith licence, there are several recognised qualifications and memberships that signal a professional has the right training:
New Zealand Certificate in Locksmithing
The most recognised formal qualification in NZ is the New Zealand Certificate in Locksmithing, delivered at vocational training levels, delivered through vocational training providers. This covers key cutting, lock installation, safe work, access control, and security hardware. Ask your locksmith whether they hold or are working towards this qualification.
Master Locksmiths Association of Australasia (MLAA)
Membership of the Master Locksmiths Association of Australasia (MLAA) is a strong indicator of professionalism. MLAA members must meet competency standards, abide by a code of ethics, and in many cases undergo police vetting. This is one of the most useful things to check when hiring.
On-the-Job Apprenticeship Training
Many experienced locksmiths in NZ have completed a formal apprenticeship under a qualified tradesperson. While this may not always result in a certificate, it represents years of hands-on, supervised training across a wide range of lock types and security systems.
Manufacturer and Product Training
Reputable locksmiths often hold product-specific certifications from security hardware manufacturers — for example, training on high-security lock brands, electronic access control systems, or master key systems. Ask whether your locksmith has relevant product training for the hardware you need installed or serviced.
Police Vetting and Background Checks
Because locksmiths have access to your home, business, or vehicle, police vetting is an important consideration. Many professional locksmiths — particularly MLAA members — undergo regular police checks. Don't be shy about asking a locksmith whether they have been police vetted. A trustworthy professional will have no issue confirming this.
Insurance: A Must-Have
Always confirm that your locksmith holds public liability insurance. This protects you if something goes wrong — for example, if a lock is damaged during installation or if a key is cut incorrectly and causes a security issue. Ask for proof of insurance before work begins. Uninsured tradespeople leave you exposed to costs that should never fall on the homeowner.
What Work Can a Locksmith Legally Do?
Locksmithing itself is not restricted work under NZ law. However, some related tasks may overlap with regulated trades:
- Electrical access control systems (electronic locks, intercoms, alarms): Installation involving electrical wiring may require a registered electrician. Check with your locksmith whether they are also a registered electrical worker, or whether they work alongside one.
- Building consent: Installing certain security hardware on fire doors or making structural changes may require a building consent. Always check with your local council. The MBIE Building Performance website has useful guidance on what requires consent and what falls under Schedule 1 exemptions.
Red Flags to Watch Out For
Be cautious of locksmiths who:
- Cannot provide a business address or verifiable contact details
- Refuse to give a written quote before starting work
- Demand cash only with no receipt
- Cannot show any qualifications, training, or insurance
- Advertise very low call-out fees but charge excessive amounts once on-site
Consumer NZ has general advice on hiring tradespeople and your rights if something goes wrong.
When to Call a Professional
Always call a qualified locksmith for:
- Lockouts — being locked out of your home, car, or business
- Lock replacement or rekeying after a break-in, lost key, or change of tenancy
- Master key system design for rental properties or commercial premises
- Safe installation, opening, or combination changes
- Security assessments and hardware upgrades
For rental properties, landlords should also be aware of obligations under the Healthy Homes standards, which include requirements around locks and latches on doors and windows — check the current Healthy Homes standards on the Tenancy Services website for the specific requirements.
