You may cancel Optimum Air for many reasons: dissatisfaction with broadband speed, poor customer service, switching to a competitor, or simply needing to reduce household expenses. Understanding your options before you act ensures you exit cleanly without unexpected charges or disputes.
Slow or unreliable broadband, uncompetitive pricing, frequent outages, and poor support are the most cited reasons customers cancel Optimum Air. If you are experiencing persistent service failures, you have legal grounds to cancel under the Consumer Guarantees Act 1993, even if your contract term has not ended. Speed degradation, dropped connections, and repeated service interruptions all breach the statutory guarantee that services must be of acceptable quality and fit for purpose.
Once you cancel, Optimum Air will cease billing you on your next cycle or on the date you specify, whichever comes first. However, you must return any equipment (modem, router, or devices) to avoid early termination fees or equipment charges. Yafee recommends photographing all returned equipment before you hand it over, as companies occasionally claim items were not received or were damaged upon return.
New Zealand's Consumer Guarantees Act 1993 and Fair Trading Act 1986 are your foundation for cancelling fairly and recovering costs if Optimum Air breaches its obligations.
Under the Consumer Guarantees Act 1993, Optimum Air must deliver services that are of acceptable quality, fit for the purpose you agreed to, and performed with reasonable care and skill. If broadband speed falls below what was promised, service is unavailable for extended periods, or support fails to resolve issues within reasonable timeframes, you have breached these guarantees.
Your legal position: You can cancel and demand a refund of fees paid, regardless of contract length, once a fault is discovered and a reasonable opportunity to fix it has been given. The burden of proof falls on Optimum Air to demonstrate that service was acceptable; you need only show that it failed to meet the standard a reasonable customer would expect. Yafee advises documenting every fault in writing and giving Optimum Air notice before you cancel, as this creates a clear record if the company later disputes your cancellation.
The Fair Trading Act 1986 prohibits misleading or deceptive conduct. If Optimum Air misrepresented contract terms, hidden fees, exit penalties, or service speeds when you signed up, you can cancel on those grounds alone. The Commerce Commission enforces this act and accepts complaints from consumers. Referencing the Fair Trading Act in your cancellation letter signals that you understand your rights and are prepared to escalate.
Optimum Air accepts cancellations by phone, post, and in person, but each method carries different risks and protections.
Calling Optimum Air's customer service team is the fastest cancellation route, but it leaves no paper trail unless you follow up in writing. Phone representatives may route you to a retention team designed to convince you to stay; remain firm and do not negotiate if your mind is made up.
Be explicit: state your full account number, say clearly "I am cancelling my account," provide your preferred effective cancellation date, and ask for a confirmation number on the spot. Request that the agent email or post a written confirmation within 48 hours. Do not accept verbal assurances alone; insist on documented proof before you hang up.
Sending a written cancellation request to Optimum Air's head office or regional office creates an audit trail that protects you if a dispute arises later. This method is especially important if you are cancelling on legal grounds (service failure or misleading conduct) because your letter becomes evidence in any future complaint to the Commerce Commission.
Write a clear letter on your own letterhead including your full name, account number, service address, and the effective cancellation date you request. State your reason for cancellation in one sentence. Sign the letter and send it via registered post or courier so you have proof of delivery. Keep a copy for your records.
If Optimum Air has a local office near you, you can visit to cancel face to face. Ask for a receipt confirming your cancellation request and the date it was processed. Take a photo of the receipt with your phone for backup.
Before you cancel, understand what charges may apply, especially if you are within a contract term or have leased equipment.
| Charge type | Amount (approx.) | When it applies | Can you avoid it? |
|---|---|---|---|
| Early termination fee | $150-$300 | Cancelling before contract end | Not if contract is active; waived if service fails |
| Equipment return fee | $50-$100 | Failure to return modem or router | Yes, return equipment promptly |
| Damage charge (if device is damaged) | $100-$250 | You damage equipment during use | Normal wear and tear does not apply |
| Final bill (prorated usage) | $0-$100 | Monthly charges up to cancellation date | No; this is legitimate |
| Refund (if service failed) | $100-$800+ | You cancel due to breached guarantees | Yes; claim under Consumer Guarantees Act |
Early termination fees apply only if you are within a contract term and cancel without a legal reason (service failure or misleading conduct). If Optimum Air promised 100 Mbps broadband and you consistently received 20 Mbps, or if the company failed to disclose a $50 monthly fee, you are legally entitled to cancel without penalty and recover fees paid for the substandard service.
Follow this procedure to cancel cleanly and protect your legal position.
You are entitled to a refund if you cancel due to a breach of the Consumer Guarantees Act or Fair Trading Act.
If Optimum Air failed to deliver service of acceptable quality, you can claim a refund of fees paid during the period of failure. For example, if broadband was unreliable for 3 months and you paid $50 per month, you may claim a $150 refund. You must notify Optimum Air in writing of the breach and allow them a reasonable opportunity (typically 10 business days) to remedy it before you demand a refund.
Your cancellation does not end the moment Optimum Air confirms it; several post-cancellation steps protect you from surprise charges or disputes.
Optimum Air will send a final bill within 10 business days, showing your account balance, any early termination fees, equipment charges, and prorated usage fees. If you are entitled to a refund (due to service failure or overpayment), deduct it from the final bill and pay only the balance. Keep a copy of your calculation in case Optimum Air disputes it later.
Processing refunds typically takes 5-10 business days once Optimum Air agrees. If no refund is credited within this timeframe, contact your bank and ask them to trace the payment.
Once the final bill is paid, your account is closed and should not appear on your credit record. If negative credit information is recorded, contact Optimum Air in writing and ask them to remove it, citing your cancellation reason. Yafee has found that companies often comply quickly when consumers reference their consumer protection rights in writing.
Once your cancellation is confirmed, you can sign up with a new broadband provider. Provide the new provider with your cancellation confirmation and final bill to avoid overlap charges or disputes over your old account.
Most cancellation disputes arise not from Optimum Air's refusal but from consumers failing to follow a clear process and leaving no documentation. You can avoid these traps entirely.
Phone cancellations are often not recorded or acted upon. Always follow a phone cancellation with a written letter within 48 hours. This second step ensures Optimum Air cannot claim you never cancelled or dispute the date you cancelled.
Failure to return equipment within 10 business days triggers equipment charges and may prevent your account from closing. Pack equipment immediately after cancellation and use a tracked courier. Yafee recommends taking photos of the packed equipment and the courier receipt to prove you sent it.
Always cross-check your final bill against your contract terms and usage records. Early termination fees should not apply if you are cancelling due to service failure. Equipment charges should not apply if you returned equipment. Dispute any charge you do not recognise within 10 business days.
If Optimum Air breached the Consumer Guarantees Act, you forfeit your refund entitlement if you do not claim it in writing before you cancel. Send a formal notice of breach and refund claim as soon as you decide to cancel. This letter is evidence if you later escalate to the Commerce Commission.
Before you cancel, consider whether renegotiating your contract might be a faster or cheaper option.
| Option | Cost | Timeline | Best for |
|---|---|---|---|
| Cancel and switch provider | Early termination fee ($150-$300) + setup costs for new provider ($0-$100) | 2-4 weeks | Serious service issues; no improvement expected |
| Negotiate a lower rate with Optimum Air | $0 (but may lose promotional rates) | 5-10 business days | Main complaint is price; service is acceptable |
| Claim refund and then cancel | $0 (refund covers early termination fee) | 3-6 weeks | Service failed; you want compensation and a clean exit |
| Stay and accept current rate | Ongoing monthly fee | N/A | Service is adequate; switching costs outweigh savings |
If your complaint is primarily cost, call Optimum Air's retention team and ask for a loyalty discount or plan downgrade. If your complaint is service quality, cancellation with a refund claim is your better option.
