is a premium shipping method which let you get shipping rates from the New Zealand Post API. It requires that your store uses NZ Dollars for it’s currency and a base country of New Zealand. The extension primarily works with mm and kgs, but other units can be converted automatically.
This extension can calculate quotes worldwide as it handles both domestic and international parcels.

Parcel Packing Method ↑ Back to top
There are 2 packing methods with NZ Post; each affects the parcels you send to the API.
Pack items individually (Default) ↑ Back to top
Each item in your cart (non virtual) will be sent to the NZ Post API. Quotes for all items will be combined for the final cost.
Pack into boxes with weights and dimensions (Recommended) ↑ Back to top
Items will be packed into pre-defined boxes and sent to the API. We recommend this option. See box-packing below for more information on this.
Box-Packing ↑ Back to top
The box packer included with this shipping method lets you group items into packages of which you define the height, width, length, weight and max-weight. The packing is mainly volume based, but does also consider item sizes too.
Setting up box sizes ↑ Back to top
Within the settings, look for the boxes setting. Click ‘add box’ to set up the boxes dimensions:
- Outer dimensions are used for parcel dimensions and are passed to the API.
- Inner dimensions are used for packing, and items will be fit within these.
- Box weight is the weight of the actual box, and will be added to the weight of the contents.
- Max weight is the maximum weight your box can hold. This includes contents weight and box weight.
How the calculation works ↑ Back to top
The packer does the following:
- Finds boxes which fit the items being packed (uses H x W x D).
- Packs all fitting items into boxes (using volume).
- The largest box which fits 100% of items is used *or* use the highest % packed box, and then pass unpacked items back (and repeat the process)
- Unpackable items are packed alone, using the item dimensions.
- All packed boxes are returned.
Customer Usage ↑ Back to top
Customers will get quotes (after inputting their address) from two places;
- The cart page – by using the shipping calculator
- The checkout page – by filling in the shipping and billing forms
Troubleshooting ↑ Back to top
No rates returned/no rates available ↑ Back to top
- Enable debug mode to see debugging information on the cart page. This will often reveal the problem.
- Check your products have sizes and weights set – without this the calculation cannot be performed.
- Check your store’s base country is New Zealand and that you are using NZ Dollars (from WooCommerce > Settings > General).
- The store address specified in general WooCommerce setting is an important part that affects several WooCommerce features, so it should be mentioned correctly. The user should also make sure that their store address is available in NZ Post API database. If not, then they must request to get their store address added into NZ Post API database.
- The plugin works correctly when both the store address and buyers shipping address details match an address within the NZ Post address database. However, when the address does not exist in the NZ Post database, or the address is entered in the wrong format, the plugin does not work.
If the buyer finds that shipping options are not coming up, then he can directly search his shipping address on NZ Post address locator here: https://www.nzpost.co.nz/tools/postshop-kiwibank-locator/. Then, they can retry and specify exactly as its appearing in the address locator search result.
- The plugin needs to be able to talk to NZ Post API. For this it uses wp_remote_post which makes use of fsockopen/CURL.
