Exceeding customer expectations for over 25 years!

Tim Bennett from Wellington

“I used to buy organic compost from a well known chain of stores but a friend put me on to Composting NZ and I haven’t looked back since!”

The Bonds, Paraparaumu

“We have regularly ordered compost from you over the last 3 years (most of our garden is made up of Compost NZ!)

We rang through an order today and you delivered it the same day. We know how busy you are at present so just wanted to say a big thanks and really appreciate all your help over the years. We still need lots more compost so we’ll be back!”

Mrs M Holmes, Te Horo

“I just love your compost and have used it for years on my gardens – I wouldn’t go anywhere else. It is also great to know that Compost NZ don’t mix any sawdust or animal bio-products in their compost!”

Alan Woods, Levin

“I am writing to you to express my thanks for your super compost product. Up until earlier this year I used fertilisers such as ‘General Garden’ & ‘Blood and Bone’.

A friend of mine suggested I wasn’t doing my soil any good, and recommended using your compost product. So I bought a cubic metre, spread it out over an area and rotary hoed it into the soil but then winter came along and put paid to the planting until recently.

Now spring has arrived, I decided as an experiment not to use any other form of fertiliser and can proudly say that the vegetables grown are 100 percent organic and are the best I have ever grown in over 40 years of gardening.”
