If you are a One NZ B customer, follow the process below.

Your current plan is shown on the Account summary page of My One NZ, under Internet services.

When changing your broadband plan (personal or business):

You can change your plan if the connection-type is the same, i.e. you're going from one ADSL plan to another ADSL plan. When this is done your next bill will show part charges for the old plan and the new.
You can schedule your plan change to happen on the 1st of the following month, so your bill will simply change to your new plan.
Your plan will be changed when the installation process is completed i.e. moving from ADSL to VDSL/Cable/Fibre. This will be dependent on when the installation process has been completed.

Open and log into My One NZ using Internet and Landline.
Under the Internet menu, select Change Account Type.
The screen will then give you the choice of which account you would like to change (if you have more than one)
Select and click Change Plan.
You will then have a selection of plans that you can change to.
If the plan you're wanting to change to is not shown i.e. Cable or Fibre but you know it is available at your address, then contact us .
