New Zealand Car Insurance Add-Ons: Windshield Coverage & Roadside Assistance Value Guide

By InsurspyPublished 16 October 2025

Introduction

In 2026, excess-free windscreen and window-glass cover and roadside assistance can be useful car-insurance additions, but neither is automatically good value for every driver. The important question is not simply whether the add-on is cheap: it is what your policy already includes, the excess that would otherwise apply, and the service limits you would actually receive.

In our editorial review, we found meaningful differences between current New Zealand policy wordings. Compare cover as well as price, because exclusions and benefits vary between policies. Compare car insurance options alongside your existing policy before renewing or changing cover.

At-a-glance comparison checklist

Item to assess	What to check	Why it matters
Glass cover already included	Is windscreen and window glass covered under the base policy, and does an excess apply?	Base glass cover does not necessarily mean an excess-free claim.
Optional excess-free glass benefit	Which glass is included, whether the claim must be glass-only, and any repair or approval requirements	The scope can be narrower or broader than the label suggests.
Vehicle technology	Whether sensors, tinting, demisters and recalibration are included when glass is repaired or replaced	Associated work may be important for sensor-equipped vehicles.
Roadside eligibility	Whether assistance follows the vehicle, the member, or both	This affects usefulness in multi-car households and when travelling in another vehicle.
Service limits	Callout cap, stand-down period, towing destination, extra charges and exclusions	Roadside assistance is not the same as unrestricted towing or immediate cover.
Duplicate cover	Any assistance already included with your car policy or another arrangement	It helps avoid paying twice for substantially overlapping benefits.

Excess-free windscreen and glass cover: what it changes

An excess is the amount you normally pay towards an accepted claim. Consumer Protection NZ notes that an excess normally applies, apart from some windscreen cover, and that a higher excess generally means a lower premium. The Insurance Council of New Zealand recommends checking both the excess payable and whether your particular claim type is exempt.

Glass cover is not uniform. Tower states that windscreen and window glass are automatically covered under its current Comprehensive and Third Party, Fire & Theft policies, while an optional windscreen excess buyout removes the excess for windscreen claims. AMI's current wording makes Excess-free glass an optional benefit across Comprehensive, Third Party Fire & Theft, and Third Party Only cover. For a glass-only sudden-and-accidental-loss claim, AMI says no excess applies; its wording includes associated tinting, demisters, rain sensors and necessary recalibration.

These examples illustrate why the policy wording matters more than an add-on name. Do not assume a general rule about chip repairs, replacement glass, sunroofs, lights, mirrors, sensors, claims history or renewal outcomes. Confirm the terms that apply to your own insurer and policy.

When glass cover may deserve closer consideration

Your current policy would require an excess for the type of glass claim you are considering.
You want more certainty about the out-of-pocket amount for an eligible glass-only claim.
Your vehicle has features connected to the glass, and the wording clearly addresses associated recalibration or components.
The quoted cost of the option makes sense against your applicable excess and the exact claim conditions.

Questions to answer before you add it

Is windscreen or window glass already covered, and what excess applies?
Does the benefit apply only where the loss is glass-only?
Does the policy distinguish a repair from a replacement?
Must you use an approved repairer or obtain approval before work begins?
What does the wording say about associated sensors, tinting, demisters and recalibration?
Could the claim affect renewal terms, a no-claims entitlement or claims history? Ask the insurer directly rather than assuming.

Roadside assistance: compare the service, not just the label

Roadside assistance can help after a breakdown, flat battery, lockout, tyre issue or other covered roadside incident, but the package varies considerably. It may be an optional paid product, included with particular cover, vehicle-based, member-based, or a combination of these.

Current examples show the range. Tower RoadWise is an optional vehicle-based service with up to three free callouts a year, a 48-hour stand-down period, and towing to the nearest repairer or place of safety when roadside mobilisation is unsuccessful. State Roadside Rescue is advertised at $39 a year with up to five callouts; it has a 24-hour stand-down period unless an immediate-cover fee is paid. State also states that additional callouts cost $50, and a customer-selected tow destination beyond the applicable destination attracts an additional $3 per kilometre.

AMI advertises Roadside Rescue as free with its Comprehensive Car insurance and with unlimited callouts. Its service page says the benefit covers the member in any vehicle and anyone driving the designated vehicle. It also lists flat-EV-battery assistance, an eligible taxi benefit capped at $80 or 50 km, and emergency fuel delivery limited to three times a year.

Those are product examples, not a ranking or a promise that a service will suit you. Eligibility, locations, exclusions, towing arrangements and definitions remain important.

Roadside assistance decision points

Callout limit: Check whether callouts are unlimited or capped, and the charge after the included allowance is used.
Stand-down: Do not assume a newly purchased plan can be used immediately.
Towing: Check whether the tow is to the nearest repairer or place of safety, or whether another destination can cost extra.
Who is covered: Establish whether cover follows one vehicle, the named member, drivers of a designated vehicle, or another arrangement.
EV support: Ask what “EV assistance” means in practice. It may mean flat-battery help or towing to safety; do not assume mobile charging is included.
Existing benefits: Check your comprehensive policy and any other arrangements first, especially if roadside cover is already included.

A practical way to decide

Use your current quote and wording rather than generic price or repair-cost estimates. Consumer Protection NZ advises consumers to compare what policies cover, not simply their price.

Download or request the current policy wording, schedule and optional-benefit terms.
Write down the excess for a glass claim and the quoted cost of any excess-free glass option.
Identify the conditions for a qualifying claim, including whether it must be glass-only and whether approval is required.
For roadside cover, compare the stand-down period, annual callouts, towing destination, out-of-pocket charges and who is eligible.
Check for overlap with cover you already have.
If a term is unclear, ask the insurer for a written explanation before buying or making a claim.

Practical Takeaway

Excess-free glass cover can be worth considering when your policy would otherwise leave you with an excess and the benefit's scope matches your vehicle and needs. Roadside assistance can be valuable when its eligibility and limits fit how and where you drive. Neither decision should rely on a market-average price, a presumed towing entitlement, or an assumed no-claims outcome.
