If you see the plans and pricing are listed in USD, it means that you are on the Trimble SketchUp (US) website.
If you are residing in New Zealand, you should always buy from BuildingPoint SketchUp NZ. This is because not only are we offering you the lowest prices but also providing you with local support in your time zone. See why buy through SketchUp NZ?
You can tell if you are on our BuildingPoint SketchUp NZ website by the browser url (sketchup.buildingpoint.co.nz) and also by the listed currency in the pricing, which should be in NZD, not USD.
If you have somehow bought in USD, see how to switch to NZD.
