Operating from Auckland and Waikato, our modern fleet of mixer trucks offer a convenient and cost-effective method of supplying concrete to commercial, industrial, rural and residential projects of all shapes and sizes. All plants have "Special Grade" status which guarantees concrete production to NZS:3104.

We operate a fully equipped laboratory in Auckland which checks consistency of raw materials and mix designs and plays a key role in new product development. Where projects call for specialised technical assistance, we have technical staff available to assist with solutions.


At the begining of 2013 Holcim's ready mixed concrete division become part of AML Limited, a joint venture of Holcim (New Zealand) Ltd and Allied Concrete Ltd, now operating as the brand Holcim Concrete.

Holcim has been at the forefront of the ready mixed concrete business since the product's inception in the mid-1950s. Because our clients rely on our ability to consistently deliver quality product to tight delivery schedules, we've learned the importance of doing the simple things well. This is reflected in the strength of our quality assurance processes and our attention to detail.

Allied Concrete's roots lie in Southland with the wider building industry interests of the HW Richardson Group. The company's involvement with ready mixed concrete started in 1976 with the acquisition of Allied Concrete Ltd which at that time had plants in Invercargill and Gore. In the ensuing years Allied Concrete has gradually expanded its operations northwards and in 1989 entered a joint venture with Milburn New Zealand Ltd (now Holcim (New Zealand) Ltd).

Collectively the company operates a modern fleet of over two hundred ready mixed trucks.


AML Limited has a network of 40 ready mixed concrete plants that supply a large share of the New Zealand ready mixed concrete market. As well as Holcim Concrete, AML Ltd also manages the Allied Concrete in the North and South Island as well as Ashby's Ready Mixed in Christchurch.
