For as long as anyone can remember, the WOF reminder has been the easiest marketing a NZ workshop does. The sticker expires, the text goes out, the car comes in, and while it’s on the hoist you find the pads at 2 mm. From 1 November 2026 that loop slows down for a big part of the fleet, and a reminder system that only knows about WOF dates will quietly stop bringing people back.
This guide covers what a reminder system needs to do after the rule change, what a reminder that actually gets booked looks like, when to send it, and how to set it up without spending your evenings on it.
What changes on 1 November 2026
The short version (full detail in our guide to the new WOF rules):
- Light vehicles aged 4 to 14 years first registered on or after 1 November 2019 move from annual to two-yearly WOFs. Those first registered between 1 November 2013 and 31 October 2019 follow on 1 November 2027.
- New vehicles get their second WOF at 4 years instead of 3.
- Vehicles aged 14 to 26 years stay annual. Vehicles over 26 years old, and pre-2000 motorcycles, drop from six-monthly to annual.
- The fine for driving on an expired WOF rises to $350.
What that means for reminders
For your newer-car customers, a WOF-only reminder now fires half as often. The oil, brake fluid and tyres on a 2021 Hilux wear at exactly the same rate they did last year, so the reminder that keeps those customers has to be keyed to service intervals, not the sticker. The WOF reminder still matters (nobody wants a $350 fine), it just can’t be the only one you send.
The three reminders every workshop needs now
1. WOF and CoF expiry
Date-based. Still the strongest prompt for the cars that stay annual, and for two-yearly cars it’s the one visit you know is coming. Expiry date comes from the rego lookup or the last inspection.
2. Service due
Time or distance, per vehicle: every 12 months or 10,000 to 15,000 km, whichever comes first. Set the next-due date at invoice time, while the odometer reading is fresh. This is the reminder that replaces the WOF for newer cars.
3. Declined work
The tyres they said "not today" to. One short, specific message at 30 days and one at 90, sent from the vehicle’s history. Under two-yearly WOFs, "next time" can be 2028.
Does it still pay? Run your own numbers. As a rough guide: say you have 500 active vehicles and, without a nudge, one in five drifts to whoever is closest when something’s due. If reminders win back half of those, that’s 50 visits a year, and at a modest $200 a visit that’s $10,000 before the work an inspection turns up. Swap in your own counts; a text costs cents and one recovered booking pays for a year of them.
What a reminder that gets booked looks like
A vague "your service might be due" email gets ignored. A specific, timely text gets a booking.
Weak
"Dear Customer, We hope this email finds you well. We wanted to remind you that your vehicle may be due for service soon. Please contact us at your convenience to book an appointment. Kind regards, ABC Motors"
Impersonal, no date, no action, and the customer has to go looking for your number.
Strong
"Hi Sarah, your Mazda 3’s WOF expires on 15 March, two weeks away. Tap [your booking link] to grab a slot, or ring us on 04 555 0123. ABC Motors, Upper Hutt"
Name, vehicle, exact date, one tap to book, and it’s obvious who sent it.
Five things to check before a template goes live:
- Their name and their vehicle. "Hi Sarah, your Mazda 3" reads like a person wrote it. "Dear Customer, your vehicle" reads like a blast.
- A date, not a vibe. "Expires 15 March" gets action. "May be due soon" gets procrastination.
- One action. A booking link, or a phone number to ring. Ask for a reply only if replies come back into your system. Hoist’s do, threaded on the customer’s file, so “reply YES”, “tap the link” and “ring us” all work.
- Who you are. Workshop name and suburb, every time. People get a lot of texts.
- Short. Two sentences of substance; the detail goes in the email version.
When to send
Too early and they forget. Too late and they’ve booked elsewhere or are driving around expired. A cadence that works for WOF expiry:
| Timing | Channel | Purpose |
|---|---|---|
| 4 weeks before expiry | Early notice with the detail: what’s due, how to book | |
| 2 weeks before expiry | SMS | Main reminder: exact date, booking link |
| 3 days before expiry | SMS | Last call: "WOF expires Monday" |
| Day of expiry (if not booked) | SMS | "Your WOF has expired. Want us to fit you in this week?" |
Service-due reminders have less of a hard deadline, so two touches is plenty: an SMS two weeks before the due date, and one more two weeks after if nothing’s booked. Use email for the first touch where you want to include detail, SMS for anything that needs to be read today. We’ve compared the two channels in SMS vs email for workshop reminders.
Four messages, then stop
If a customer hasn’t booked after four reminders, they’ve made a choice. Pestering them past that point costs you the relationship you were trying to keep. If anyone asks to stop getting reminders, stop the same day.
Setting it up so it runs itself
Sending reminders by hand works for 50 vehicles and collapses at 400. Here’s the setup in workshop software such as Hoist:
Get the dates in
Every vehicle needs a WOF (or CoF) expiry and a next-service-due date. Rego lookup from official NZ vehicle records brings the WOF expiry in with the vehicle; you set the service-due date yourself at invoice time, from the odometer and the interval. A mobile number on every customer record is the other non-negotiable.
Set a rule per reminder type
WOF, CoF and service reminders each get their own schedule (for example email at 4 weeks, SMS at 2 weeks and 3 days) and their own template. Auto-send can be on or off per rule, and you can send any reminder manually whenever you like, which is how declined-work follow-ups go out.
Test on yourselves first
Put your own cars and your staff’s cars through the rules for a week before customers see anything. Check the name, the vehicle, the date and the link all fill in correctly on a real phone.
Count the bookings
Once a month, look at how many reminders went out and how many turned into a booking. If the rate is poor, fix the message or the timing first; if it’s good, expand the service-interval rules to the rest of the fleet.
Two housekeeping habits keep the list worth sending to: clear out dead numbers and bounced emails when you see them, and remove anyone who asks, politely and immediately. A smaller list that books beats a big one that ignores you.
The 1 November deadline is the point
Customers whose cars go two-yearly in November won’t notice anything for a year or more, and neither will you. The bookings that don’t happen in 2027 are decided by whether service-interval reminders are running by the end of 2026. Get the dates into the system, switch the rules on, and let the reminder do the chasing you’ve never had time for.
