How does shipping work?
Freight is calculated automatically at checkout for smaller orders. For bulkier consignments, we’ll be back in touch to confirm a freight price. See our Shipping Information for more details.
North Island Customers: Shipping costs can be significant (and sometimes exceed the plant value), so combining items into a larger order helps keep it cost-effective.
