How to Safely Sell Your Phone Online in NZ (Step-by-Step Guide)

Selling your phone online in NZ should be simple — and with a bit of preparation, it is.

If you’re upgrading or clearing out an old device, or selling a phone online there are a few quick steps that make the process smooth from start to finish.

Here’s how to get your phone ready properly.

Step 1: Back up anything you want to keep

Before you send your phone off, take a moment to save anything important like photos, contacts, or notes. Apple has a guide on how to backup your device here: https://support.apple.com/en-nz/108771

For iPhone:

  • Use iCloud backup

  • Or back up to your computer

For Android:

  • Use Google Backup

  • Or transfer files to your computer

Once that’s done, you’re ready to move on.

Step 2: Sign out of your account (iCloud or Google)

This step is important to make sure the phone is ready for its next user.

For iPhone:

  • Go to Settings

  • Tap your name

  • Scroll down and tap Sign Out

For Android:

  • Go to Settings

  • Accounts

  • Remove your Google account

Step 3: Turn off Find My iPhone

For iPhones, this is a key step.

  • Go to Settings

  • Tap your name

  • Tap Find My

  • Turn off Find My iPhone

This ensures the device is fully ready to be processed.

Step 4: Factory reset your phone

Once everything is backed up and accounts are removed, it’s time to reset the device. 

For iPhone:

For Android:

This returns the phone to its original state — ready for its next use.

Step 5: Remove your SIM card

Quick but important:

  • Take your SIM card out before sending the phone

That’s your number and plan sorted.

Step 6: Give it a quick clean

You don’t need to overthink this — just a simple wipe down:

  • Clean the screen and body

  • Remove dust or fingerprints

If you’ve got the original box, that’s a bonus — but not essential.

Step 7: Package it properly for courier

If you’re sending your phone, a bit of care here goes a long way.

Best way to package:

  • Wrap the phone in bubble wrap or soft material

  • Use a sturdy box

  • Make sure it doesn’t move around inside

  • Seal it securely

The goal is simple: it arrives in the same condition you sent it.
