Frequently Asked Questions

How Do I Place an Order?

You can purchase through one of our retailers, or directly through our website. Buying through our retailers offers free shipping and expert support.

If you need help, call us at 0800 946 837 or email sales@wintergardenz.co.nz.

Are Your Greenhouses Made in New Zealand?

Yes! Our greenhouses are made in our factory in Kumeu and are Certified New Zealand Made. Designed for local conditions, they offer durability, support, and peace of mind.

Do I Need Consent?

Most kitset greenhouses don’t require consent if under 30 square metres. Larger models or public installations may require documentation, which we can help provide.

Kitset Greenhouse Delivery

Greenhouses are shipped to the nearest Mainfreight depot due to weight. You’ll need a trailer to collect them, and the depot will forklift the crate onto it.

Learn more on our shipping page.

What Tools Do I Need for Assembly?

  • Cordless impact driver (with supplied 10mm nut setter/socket)
  • Phillips head screwdriver
  • Set square, spirit level, tape measure
  • Scissors or sharp knife
  • Bucket of warm soapy water (helps with rubber beading)

Where Can I Find Base Dimensions?

Go to the product page of your greenhouse size (e.g., 10x16ft glasshouse) and click 'Download Foundation Page'.

How Difficult Is Assembly?

Watch our installation videos to decide. Most greenhouses can be built with patience and time, but if you'd rather have it assembled professionally, check out our installation services.

For reference, a 8x8ft greenhouse takes two people about a day to build.
