How to cancel Mainfreight by mail
Gather your account details
Have the name and email on the account and, if you have one, an account or customer number to hand. The details in the letter need to match what Mainfreight has on file.
Set out the request
Ask Mainfreight to cancel the account, stop all further charges and confirm in writing. Postbye prepares the letter from our English template, with the subject line “Subject: Cancellation Request – [your name]”.
Send it by certified mail
Send the letter to the Auckland mailing address shown below by certified mail. Keep the tracking number safe.
Keep the delivery receipt
Once the letter is delivered, the date on the receipt is the date Mainfreight was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Mainfreight cancellation letter goes
Mainfreight takes its post at 2 Railway Lane; Otahuhu, 1062 Auckland, New Zealand, which is where a cancellation letter belongs.
The postcode 1062 belongs to Auckland, New Zealand, so this is where the envelope is delivered.
The letter is addressed “To Whom It May Concern,” and its details block uses the labels Account holder, Billing address on file and Email on file.

Before you cancel Mainfreight, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
Start on mainfreight.com: the account area there shows who actually bills you, which decides who the request must reach.
