How to cancel Powerco by mail
Note your account details
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Powerco names the right account the first time.
Draft the request
The letter asks Powerco to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Cancellation Request – [your name]”. Postbye fills it in from our English template.
Send it by certified mail
Use certified mail for the 4312 New Plymouth address in the next section, so the post office records the delivery. Write down the tracking number.
File the delivery record
The receipt dates your request. Look at your next statement for any Powerco charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Powerco cancellation letter goes
Powerco lists 35 Junction Street; Welbourn; New Plymouth, 4312 New Plymouth, New Zealand as its mailing address.
The postcode 4312 belongs to Taranaki, New Zealand, so this is where the envelope is delivered.
Inside, the salutation reads “To Whom It May Concern,”, followed by your details under Account holder, Billing address on file and Email on file.

Before you cancel Powerco, check these
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
