It will be helpful to people reading your questions if you add your hardiness zone to your profile.
Here's a map with New Zealand hardiness zones:
https://www.plantmaps.com/inte...
Find your zone and then add it to your profile by following these instructions:
On the top of the browser page is a tool bar, on the right hand side you will see an envelope, a bell, and your profile picture/avatar(currently an acorn), click on the acorn.
In the drop down menu click on "Your Profile".
On the page that comes up click on "Change your public profile".
On that page go down to "Your USDA Hardiness Zone" and choose the zone you found on the map.
You can also change your profile picture at the bottom of the form where it says "Your avatar photo" when you browse for an image and select it, it won't get uploaded and changed until after you click the "Save your changes" button.
I hope that's helpful 🙂
