In New Zealand, locksmiths and security consultants both help keep your home or business safe, but they do quite different jobs. A locksmith focuses on the physical side of security — locks, keys, and access hardware — while a security consultant takes a broader, strategic view of your overall security setup. Knowing which professional to call can save you time and money.
What Does a Locksmith Do?
A locksmith is a tradesperson who specialises in the installation, repair, and maintenance of locks, deadbolts, door hardware, and key systems. In New Zealand, locksmiths typically offer services such as:
- Emergency lockouts — getting you back into your home, car, or business when you're locked out
- Lock installation and replacement — fitting new deadbolts, mortice locks, or padlocks to doors and gates
- Rekeying — changing the internal pins of a lock so old keys no longer work (useful after moving into a new home)
- Master key systems — setting up a hierarchy of keys for rental properties or commercial buildings
- Safe opening and servicing — opening safes when combinations are lost and servicing safe mechanisms
- Key cutting and duplication — cutting new keys from existing ones or from a code
Locksmiths work with physical, mechanical, and increasingly electronic access control hardware such as keypad locks, smart locks, and card readers. Many NZ locksmiths are members of the Master Locksmiths Association of Australasia or similar industry bodies, though locksmithing is not a formally licensed trade under NZ law in the same way that electrical or plumbing work is.
What Does a Security Consultant Do?
A security consultant (sometimes called a security advisor or security systems specialist) takes a higher-level approach. Rather than just fitting a lock, they assess your entire property and recommend a layered security strategy. Their work may include:
- Conducting a security risk assessment of your home or business premises
- Recommending and designing alarm systems, CCTV camera networks, and intercoms
- Advising on lighting, fencing, and landscaping changes that deter intruders
- Specifying access control systems for commercial or multi-unit residential buildings
- Reviewing policies and procedures for businesses (e.g. key management, visitor sign-in)
- Liaising with alarm monitoring companies and integrating systems
Security consultants often hold qualifications in security management or electronics, and those who install alarm systems or CCTV may need to be licensed under the Private Security Personnel and Private Investigators Act 2010, administered by the New Zealand Police. If you're engaging a security consultant for a commercial project, always check they hold the appropriate licence for the work they're performing.

Do You Need One or Both?
For many homeowners, a locksmith is the first port of call — especially after a break-in, when moving into a new property, or when a lock is worn or damaged. A good locksmith can also advise on whether your current locks meet a reasonable standard for your area.
If you're building a new home, running a business, managing a rental portfolio, or have experienced repeated security incidents, a security consultant adds real value by looking at the big picture. They can identify vulnerabilities you might not have considered, such as poorly lit entry points or weak perimeter fencing.
Some larger locksmith companies in NZ offer both services under one roof, so it's worth asking what's included when you get a quote.
NZ Building Code and Lock Standards
When installing new locks as part of a building project, it's worth knowing that the NZ Building Code (particularly clauses relating to means of escape and door hardware) and NZS 4520 (Locks and Latches for Doors in Buildings) set minimum standards for hardware in certain situations. If your lock work is part of a larger building project, check with your local council whether a building consent is required — most straightforward lock replacements are exempt under Schedule 1 of the Building Act, but always confirm with your council if you're unsure. MBIE Building Performance is a good starting point for understanding consent requirements.
For rental properties, landlords should also be aware of Healthy Homes Standards, which include requirements around security stays on windows. Tenancy Services has detailed guidance on what's required.
When to Call a Professional
- Call a locksmith when you're locked out, need a lock replaced or rekeyed, want to upgrade to a deadbolt, or need a master key system set up.
- Call a security consultant when you want a full security review, are installing an alarm or CCTV system, or are setting up access control for a commercial building.
- Check licensing — if someone is installing a monitored alarm system or carrying out security guarding work, verify they hold a current licence under the Private Security Personnel and Private Investigators Act.
- For any work involving electrical wiring (such as hardwired alarms or electric strikes), this is restricted electrical work that must be carried out by a registered electrician. Check the Electrical Workers Registration Board (EWRB) to verify a tradesperson's registration.
