Terms of sale

Last updated 18 October 2026

These terms apply when you buy from Personal Breathalysers, 10 Griffin Road, Maungaturoto 0520.

Prices and payment

  • All prices are in New Zealand dollars and include GST.
  • Delivery within New Zealand is free.
  • A 3% card fee is added to device purchases. It's shown at checkout before you pay. There's no card fee on the calibration service.
  • Payment is taken securely by Stripe when you place your order. You'll get an emailed receipt straight away.
  • If we can't fill your order — for example if an item is out of stock or was shown at the wrong price — we'll contact you and give you a full refund if you don't want to go ahead.

Delivery and returns

See Shipping & returns for delivery times and how to return an item.

Using a personal breathalyser

Personal breathalysers give an estimate of your breath alcohol level. Readings can be affected by recent drinking (alcohol levels often keep rising for up to an hour after your last drink), mouth alcohol, temperature, and when the device was last calibrated. Please keep these points in mind:

  • A reading is a guide only. It isn't a legal defence and doesn't replace an official police test.
  • If you've been drinking and you're in any doubt, don't drive.
  • Follow the instructions that come with your device, and have it calibrated as recommended.

See NZ drink-driving limits for the current legal limits.

Your rights under New Zealand law

Our products come with guarantees under the Consumer Guarantees Act 1993 that can't be excluded, including that they're of acceptable quality, fit for their purpose and match their description. If something goes wrong, you may be entitled to a repair, replacement or refund. Nothing in these terms limits your rights under that Act or the Fair Trading Act 1986.

If you're buying for a business (for example, devices for workplace testing), you agree that the Consumer Guarantees Act doesn't apply, as section 43 of that Act allows. Your rights under these terms and the manufacturer's warranty still apply.

Warranty

Each device comes with a 12-month manufacturer's warranty from the day it's delivered. It covers faults in materials and workmanship. It doesn't cover:

  • damage from drops, liquids, misuse or opening the device
  • normal sensor drift — fuel cell sensors need regular calibration to stay accurate
  • mouthpieces and batteries

To make a claim, contact us with your order details and a description of the problem. The warranty is in addition to your rights under the Consumer Guarantees Act.

Calibration service

  • After you buy the service we'll email you instructions for sending your device in. Freight is free both ways within New Zealand.
  • We calibrate your device and send it back within 2 business daysof receiving it.
  • If we find your device can't be calibrated — for example because its sensor has reached the end of its life — we'll contact you before doing anything else, return the device and refund the calibration fee.

Liability

Subject to your rights under New Zealand law, we're not responsible for decisions you make about driving or work based on a reading, or for any resulting loss, fine or penalty.

General

These terms are governed by New Zealand law. We may update them from time to time; the version on this page when you place your order is the one that applies to it.
