A home security assessment is a professional walkthrough of your property where a qualified locksmith identifies weak points in your home's physical security and recommends practical improvements. In New Zealand, these assessments are available from most locksmith businesses and typically take between 30 minutes and two hours depending on the size of your home. Whether you've just moved in, had a break-in nearby, or simply want peace of mind, knowing what to expect helps you get the most out of the visit.
What Happens Before the Assessment
When you book a home security assessment, the locksmith will usually ask a few questions upfront — the size of your property, the number of entry points, whether you have an existing alarm system, and whether you rent or own. If you're a tenant, it's worth checking your lease and speaking with your landlord before making any changes, as some modifications may require permission. Tenants and landlords in New Zealand also have obligations under the Healthy Homes standards. Note that the Healthy Homes standards cover areas such as heating, insulation, ventilation, moisture and drainage, and draught stopping — check Tenancy Services for the current requirements and how they may relate to doors and windows.
Have a list of any concerns ready — for example, a door that doesn't close properly, a window lock that feels loose, or a gate that's easy to climb.
Checking Entry Doors and Locks
The locksmith will start with your main entry points — front door, back door, internal garage door, and any side access doors. They'll assess:
- Lock grade and quality — Many NZ homes still have older, lower-grade deadbolts or simple latch locks that can be bypassed quickly. A locksmith will check whether your locks meet a recognised standard such as AS/NZS 4145 (the Australian/New Zealand standard for mechanical locks).
- Strike plate and door frame strength — A quality lock is only as good as the frame it's fitted to. Weak strike plates with short screws are one of the most common vulnerabilities found in NZ homes.
- Door alignment and gaps — Warped doors or large gaps around the frame can make forced entry easier.
- Deadbolt throw length — A longer bolt throw provides better resistance to kick-in attacks.
If your locks are outdated, the locksmith may recommend upgrading to a Grade 1 or Grade 2 deadbolt, or a high-security cylinder that resists picking, drilling, and bumping.
Windows and Secondary Entry Points
Windows are frequently overlooked but are a common entry point for opportunistic burglars. The locksmith will check:
- Whether window locks are present and functioning
- Whether louvre or jalousie windows (common in older NZ homes) can be easily removed from outside
- The condition of sliding door locks and anti-lift devices
- Whether security stays or window restrictors are fitted, particularly for upper-storey windows
They'll also look at secondary entry points such as skylights, pet doors, and roof access hatches.
Exterior and Perimeter Security
A thorough assessment goes beyond the building itself. The locksmith will walk around the outside and consider:
- Lighting — Poor lighting around entry points is a significant risk factor. Motion-activated lights are a cost-effective deterrent.
- Visibility and sightlines — Overgrown hedges or fences that conceal entry points can assist a burglar.
- Gate and fence security — Padlock quality, gate latch design, and fence height all contribute to perimeter security.
- Garage security — Roller door mechanisms, internal access doors, and whether the garage can be accessed from outside without a remote.
Alarm Systems and Smart Security
Many locksmiths are knowledgeable about alarm systems, smart locks, and video doorbells, though installation of alarm systems may be carried out by a separate security company. During the assessment, they may discuss:
- Whether a monitored alarm system would suit your property
- Smart lock options — keypad, Bluetooth, or Wi-Fi enabled locks that allow keyless entry and remote access
- Integration with existing home automation systems
Note that any electrical work involved in installing hardwired alarm systems or smart home devices must be carried out by a registered electrician. Check the Electrical Workers Registration Board (EWRB) to verify a tradesperson's registration before they do any electrical work in your home.
The Written Report and Recommendations
At the end of the assessment, a professional locksmith should provide you with a clear summary of findings — either verbally or in writing — covering:
- Identified vulnerabilities, ranked by priority
- Recommended products or upgrades (with approximate costs where possible)
- Any urgent issues that should be addressed immediately
A good locksmith won't pressure you into unnecessary upgrades. Ask questions, get a second opinion if needed, and prioritise the changes that offer the best security improvement for your budget.
When to Call a Professional
While some minor security improvements — like adding a door chain or fitting a window stay — can be DIY jobs, most lock installations and upgrades are best left to a qualified locksmith. Incorrect installation can leave a lock less secure than before, or damage your door frame. If you're unsure whether a job is within your skill level, it's always safer to call a professional.
For any work involving electrical components (hardwired alarms, electric strikes, or access control systems), you must use a registered electrician — this is restricted work under the Electricity Act. You can verify registrations at EWRB.
