Written by Cabling For U — Auckland access control and security cabling specialists.
Locks with keys were how we did security for a hundred years. In 2026, the majority of Auckland commercial sites we walk into are moving to one of three modern options: RFID cards, mobile credentials, or biometrics — usually with cloud-based management. This guide explains what each option gives you, what it costs, and where we see the trade-offs play out.
What problem is access control actually solving?
- Lost keys — no more rekeying the building when an employee walks out with a master key
- Audit trail — who went where, when, and for how long
- Scheduled access — cleaners after hours, contractors during a window, staff only weekdays
- Remote revocation — instantly disable a credential when someone leaves the company
- Zone control — sales in the front door, not in the server room
- Compliance — audit logs for ISO 27001, SOC 2, Privacy Act 2020
The three credential types
RFID cards and fobs
Still the workhorse for Auckland commercial sites in 2026. Reliable, cheap, familiar. Modern systems use DESFire EV3 or LEGIC encrypted cards — not the old 125 kHz cards from 10 years ago, which are trivially cloned. Expect NZD 8–15 per card.
Mobile credentials
Your phone becomes your key via Bluetooth, NFC or a dedicated app. Users love them: no physical card, instant provisioning, works even with flat battery via NFC on most modern phones. Monthly licence fee (typically NZD 2–5 per user per month). The right choice for sites with high staff turnover.
Biometric (fingerprint, face, palm vein)
Hardest to defeat and most secure. Slower to enrol and has privacy implications under the Privacy Act 2020 — you need a documented policy and opt-out options. Best for server rooms, pharmacy dispensaries, cash handling and high-security zones. Expect 2–4× the cost of RFID readers.
Cloud-based vs on-prem access control
Cloud-based (the 2026 default)
- No on-site server to maintain
- Manage from any browser or phone
- Automatic software updates and security patches
- Typical subscription: NZD 10–25 per door per month
- Best for: multi-site operators, anyone without dedicated on-site IT
On-prem
- All data stays on your own server
- No recurring subscription
- Higher upfront cost, requires IT to maintain
- Best for: high-security, compliance-driven, or no-internet sites
Most Auckland SMBs we install for in 2026 choose cloud. It’s faster to deploy and the ongoing cost is roughly what a part-time IT contractor would charge to maintain on-prem.
Door hardware matters more than the reader
The reader is the part people notice. The locking hardware is the part that actually secures the door. Four options, each with trade-offs:
- Magnetic lock (maglock): Silent, fail-safe (unlocks on power loss for life safety). Common on glass doors. Needs power and fire-alarm interlock.
- Electric strike: Cheap, easy install, works with existing door hardware. Fail-safe or fail-secure options. Clicks when unlocked.
- Electrified mortice lock: Most professional option, hidden inside the door. Works with all-glass and commercial timber doors. Higher install cost.
- Wireless lock: Battery-powered, no cabling. Convenient for retrofit. Battery must be managed — not every door is a candidate.
Cabling considerations
Access control cabling is mostly low-voltage and straightforward, but the details matter:
- Reader cable: 6-core shielded (18 AWG typical), 30 m max run per reader
- Lock power: dedicated 2-core 18 AWG from power supply to lock, run separately from reader cable to reduce noise
- Request-to-exit (REX): 2-core to internal PIR or push button
- Door position sensor: 2-core to magnetic reed switch
- Fire alarm interlock: required for maglocks — links to fire panel relay
- Power supply: 12V or 24V DC, UPS-backed, separate circuit from building lighting

Integration with CCTV, alarm and HR systems
- CCTV: link every door event to the nearest camera so you can see who actually used the card
- Burglar alarm: disarm the alarm automatically when the first authorised card is presented in the morning
- HR system: automatic deprovisioning when an employee is marked as terminated
- Building management: turn on lights, AC, printers for the first arrival
This is where the real ROI lives — the cards stop being just keys and start being the orchestrator of your whole site.
Typical Auckland access control costs (2026)
- 1-door cloud system with RFID + electric strike: $2,500–$3,800 installed, plus NZD 15–25/mo
- 4-door commercial system (reception, back door, server room, general access): $8,000–$14,000 installed, plus ~NZD 60–80/mo
- 12-door medium site with biometric on server room, mobile credentials: $22,000–$38,000, plus ~NZD 180–250/mo
- Multi-site 30-door cloud system with ANPR, visitor management: $60,000–$120,000, plus ~NZD 450–600/mo
Frequently asked questions
What is the difference between RFID and mobile credentials?
RFID uses a physical card or fob tapped against a reader. Mobile credentials use your smartphone via Bluetooth or NFC to unlock doors — no card required. Mobile is faster to provision, cheaper per user over time, and preferred by staff, but requires a smartphone and usually a monthly subscription.
Is cloud-based access control secure?
Yes, if you pick a reputable vendor. Modern cloud access control uses end-to-end encryption, per-door controllers that keep working if internet drops, and SOC 2 audited data centres. Look for vendors that publish their security practices and offer MFA for administrators.
Can access control be retrofitted to an Auckland heritage building?
Yes. We use wireless door locks or electrified mortice locks with minimal aesthetic impact. Cabling runs in existing service voids or surface-mounted conduit. We frequently retrofit Auckland CBD heritage buildings without compromising the protected facades.
Do I need biometric readers or are cards enough?
For most Auckland offices, encrypted RFID cards or mobile credentials are sufficient. Biometric readers make sense for server rooms, pharmacy dispensaries, cash handling areas, or any zone where you absolutely must know the identity behind the credential — not just that someone with a card was there.
What happens if the power goes out?
Depends on fail-safe vs fail-secure configuration. Magnetic locks are fail-safe (unlock on power loss for life safety). Electric strikes are usually fail-secure (stay locked on power loss). Good systems include UPS backup so doors keep working for 30 to 60 minutes during outages.
How long does access control installation take?
A single-door cloud install is typically a day. A 4-door commercial system takes 2 to 4 days. A 12-door medium site is 1 to 2 weeks. Cabling is the slowest part — the software configuration is usually a single day once doors are cabled.
