Green Slip Renewal in NSW: CTP and Rego Step by Step

Your renewal notice has landed and it says you need a green slip before you can renew. That one line raises the usual questions: which comes first, can you do 6 months, does the car need a pink slip, and what happens if you're already late? The short version is green slip first, rego second, same term for both. We checked the steps below against Service NSW, NSW Government and SIRA pages on 30 October 2026.

GreenSlipInsurance.com.au is a general information site operated by Dominet BV. This page is general information only and is not financial, legal or insurance advice. It does not consider your objectives, financial situation or needs. We are not an insurer or broker, we don't sell green slips and we don't recommend any insurer. SIRA (the State Insurance Regulatory Authority) is the official source of green slip information in NSW, so check its website or your insurer before you act. Facts were checked on 30 October 2026. Read our general information notice. Rego rules are set by Transport for NSW and Service NSW, so check your renewal notice for your own dates.

Green slip first, then rego

A green slip is compulsory third party (CTP) insurance, and you need a current one to renew registration. The NSW Government's How to renew vehicle registration page lists the exceptions: trailers, caravans and conditionally registered vehicles have CTP built into the registration, so there's no separate green slip to buy.

The green slip and the rego are two separate payments to two different organisations. You pay the green slip to a CTP insurer. You pay the rego (registration fee and motor vehicle tax) to Transport for NSW through Service NSW. Paying one doesn't do the other.

Your renewal notice

Service NSW says renewal notices are sent 4 to 6 weeks before the due date. The notice tells you whether the vehicle needs a safety inspection (a pink slip) this time.

Your CTP insurer may also send a renewal offer. Under SIRA's Motor Accident Guidelines (version 10.1, from 12 December 2025), that offer must list the pricing factors used, such as the youngest driver's age and the vehicle's age, explain how to correct a wrong factor, and name the licensed insurer. Read it before you pay. SIRA says wrong details can lead to an adjustment charge, the registration being cancelled with reinstatement fees, and penalties.

Renewing step by step

1. Check the notice. Note the due date, the term you want and whether an inspection is needed.
2. Buy the green slip. Any licensed NSW CTP insurer can sell it to you. SIRA's How to buy a Green Slip page says to have the number plate, the VIN or chassis number and your licence or photo card number ready.
3. Get the pink slip if needed. Only an Authorised Inspection Scheme station can do it, and it sends the result to Transport for NSW electronically.
4. Renew the rego. Most insurers send your CTP details electronically too, so once everything is through you can renew online with Service NSW and pay the registration.

Steps 2 and 3 can happen in either order. Both just need to be done before step 4. Our green slip vs pink slip guide explains the inspections.

12 months or 6 months

SIRA says green slips are generally sold for 12 months or 6 months (fleet owners and dealers have other options). The NSW Government says the length of your CTP policy must match your registration term, so a 6 month rego needs a 6 month green slip.

Service NSW lists which vehicles can use shorter terms:

• 6 month registration is available for most light vehicles up to 4.5 tonnes gross vehicle mass, including motorcycles and trailers
• 3 or 6 month registration is available for trailers and heavy vehicles over 4.5 tonnes

A 6 month green slip isn't always exactly half the 12 month price. SIRA's guidelines let insurers add a capped surcharge to short policies (for 6 months, up to $5 plus up to 1.5% of the annual premium, before halving), then GST and a pro rata share of the Fund Levy. Our green slip cost guide has the detail.

The 21 day rule. Both Service NSW and the NSW Government say that if you renew for 6 months, you must pay the CTP and renew the registration no later than 21 days after the rego expires.

A change of term can also change the inspection rules. Service NSW says you'll need an inspection if the new expiry date would be more than 12 months after the last renewal that needed one, for example going from a 6 month term back to 12 months. The NSW Government suggests asking for a new renewal notice when you change terms, so you can see what's required.

Renewing early or late

The NSW Government says you can renew up to 3 months before the due date and within 3 months after the rego has expired. Service NSW adds two details:

• Early: you need a renewal notice to renew early.
• Late: the new registration period starts from the day you pay, but the expiry date stays the same. You don't get a full year.

Past 3 months, it's no longer a renewal. Service NSW and the NSW Government treat a vehicle unregistered for more than 3 months as needing to be registered again, which includes an AUVIS inspection (blue slip). Our guide to unregistered, new and interstate vehicles covers that process.

Expired rego and your green slip

The risk most people underestimate is the gap. Service NSW says that if you don't renew by the expiry date, the vehicle is unregistered, driving it is illegal with heavy penalties, and it can mean the vehicle isn't covered by CTP insurance. SIRA's page on failing to take out CTP is blunter: your CTP insurance is not valid until your vehicle is registered, and driving unregistered can bring heavy fines and in some cases jail.

So a paid green slip on its own doesn't make the car legal to drive. The rego has to be renewed as well.

Two smaller rules from the NSW Government: CTP policies have a use-by date, so check yours hasn't passed before you renew, and vehicles registered in NSW must be insured with a NSW CTP insurer.

Changing insurer at renewal

You don't have to renew with the insurer you had last year. SIRA's list of CTP insurers (updated 13 April 2026) names six licensed insurers: AAMI, Allianz, GIO, NRMA, QBE and Youi. SIRA says all green slips give the same level of CTP cover, though the prices may differ.

SIRA's free Green Slip Price Check shows quotes from all of them. Searching with your licence or billing number gives the most accurate figure, and SIRA says to confirm the price with the insurer before you buy. Our guide to comparing green slips explains the options.

Pensioners with free rego

SIRA says pensioners who have free registration may have their CTP renewed automatically. It's worth checking your renewal paperwork, or with SIRA or your insurer, to confirm what applies to your vehicle.

What this means for you

Put the renewal notice next to your green slip offer and check three things: the due date, the term, and whether a pink slip is needed. Then buy the green slip, get the inspection if one is required, and renew the rego before the expiry date.

If you're choosing 6 months, keep the 21 day limit in mind. If you're already past the expiry date, don't drive the vehicle until the rego is renewed, and if it's been more than 3 months, expect to register it again with a blue slip.

Frequently asked questions

Do I pay the green slip or the rego first?

The green slip. The insurer sends your CTP details to Transport for NSW electronically, and then you can renew the registration with Service NSW.

Can I get a green slip for 6 months?

Yes, for vehicles that can be registered for 6 months, which includes most light vehicles and motorcycles. The green slip term must match the rego term, and a small capped surcharge can apply.

Does buying a green slip renew my rego?

No. They're separate payments. SIRA says CTP insurance isn't valid until the vehicle is registered, so you still need to renew with Service NSW.

How early can I renew my green slip and rego?

Up to 3 months before the due date, as long as you have a renewal notice. Your expiry date doesn't change when you renew early.

What if my rego expired more than 3 months ago?

It can't be renewed in the usual way. The vehicle needs to be registered again, which includes an AUVIS (blue slip) inspection and a new green slip.

Do I have to stay with the same CTP insurer?

No. You can buy from any licensed NSW CTP insurer. SIRA's Green Slip Price Check shows quotes from all six.
