Code Dropping out with latest Woo update

Hi @natemossp,

Thanks for the heads-up and clear screenshot, much appreciated!

I’ve now tested the plugin with WooCommerce 7.1.0 and can confirm I’m seeing the same behaviour. I’ll look into resolving this when I next get a free moment.

What should be happening is the non-rural zones have their zone region data assigned from WooCommerce’s built-in region list. The temporary fix for now (presuming you don’t downgrade to an earlier version of WooCommerce) is to manually reassign the correct zone regions for the North Island and South Island zones, as so:

North Island: Northland, Auckland, Waikato, Bay of Plenty, Taranaki, Gisborne, Hawke’s Bay, Manawatu-Wanganui, Wellington

South Island: Nelson, Malborough, Tasman, West Coast, Canterbury, Otago, Southland

Hi again @natemossp

I’ve made an update to the plugin to support the new region code format in WooCommerce 7.1.0 and added an update to the FAQ ??

In the interests of having a fix quickly in place, this update will only take effect when installing a fresh version of the plugin (i.e. deleting the plugin-generated shipping zones before reactivating the plugin). I need to do some thinking about whether it’s worth extending the plugin to update shipping region codes generated prior to the latest WooCommerce release.

This means, depending on your current shipping zones configuration, you may still find it easiest to manually add back in the zone regions that disappeared from the North Island and South Island shipping zones.

Thanks again for spotting the issue!

To close this out, I’ve just tested manually setting up zone regions with a fresh install of WooCommerce 7.0.1, then upgrading to 7.1.0. I’m seeing the same behaviour: the regions are no longer assigned to a zone after the upgrade.

Hopefully can be addressed on the WooCommerce side ?? https://github.com/woocommerce/woocommerce/issues/35535

WooCommerce have now confirmed it’s a bug in the 7.1.0 release, likely to be addressed shortly: https://github.com/woocommerce/woocommerce/issues/35535#issuecomment-1311654228

Thanks again for taking the time, @natemossp !

@chthnc My journey on this – I had to uninstall New Zealand Shipping Zones for WooCommerce plugin, delete the shipping zones (important step) then reinstall the updated plugin and set the shipping methods and fees back up again.

I may initially have ran the plugin as an update moments before the WooCommerce update, for whatever that may have factored, but it didn’t work. Customers notified us of the error. Rolled back to previous version of New Zealand Shipping Zones for WooCommerce – still didn’t work (for reasons you described above) then decided to uninstall your plugin completely and reinstall the new version. Success.

Thank you for a great plugin and getting on top of issues caused by WooCommerce.

I really appreciate this support thread as all the North and South regions had disappared which meant no shipping costs were being calculated.

The quickest solution for me was to manually input the regions in as suggested above:

North Island: Northland, Auckland, Waikato, Bay of Plenty, Taranaki, Gisborne, Hawke’s Bay, Manawatu-Wanganui, Wellington

South Island: Nelson, Malborough, Tasman, West Coast, Canterbury, Otago, Southland
