AML to Sell Concrete Plants to Allied Concrete and Holcim

Today, AML Limited (AML) is announcing the intended sale of its concrete plants in New Zealand

AML is a joint venture between Allied Concrete Limited (ACL) and Holcim New Zealand Limited (Holcim). This joint venture operates a number of concrete plants, which trade under the brands of Allied Concrete in the North Island and Ashby’s Ready Mixed in the South Island.

ACL and Holcim have mutually agreed to further their business strategies independently and conclude this joint venture. Subject to New Zealand regulatory approvals, the new operational arrangements will be in place from November 2023.

As a result of this, Holcim will operate the majority of plants (20) in the North Island under the Holcim brand, which include Avondale, Bombay and Horotiu. Holcim will also operate Ashby’s Ready Mixed in Christchurch, under its existing brand.

Plants to be operated by Holcim:

Waipapa Morrinsville Whakatane Palmerston North
Bombay Tauranga Taupo Levin
Avondale Rotorua Hastings Masterton
Horotiu Whitianga New Plymouth Wellington (Kiwi Point)
Upper Hutt
Matamata Tairua Hawera - Stratford Ashby’s Ready Mixed

ACL (owned by H. W. Richardson Group Limited) will operate the remaining Silverdale, Penrose, and Hautapu Rd (Cambridge) plants in the North Island. The cessation of the joint venture will not affect any other Allied Concrete plants in the South Island.

Both ACL and Holcim are committed to continuing to deliver outstanding service, maintaining their high levels of health and safety and ensuring continuity for staff, customers and suppliers.
