About Us

Mason Contractors began in Warkworth in 1973 with one man, Alastair Mason,  some shovels and picks, a concrete mixer and a ute. The first concrete company in the area to specialise in footings and floors, it later expanded into contracting services with machinery and trucks, as well as builder and contractor supplies.

Masons sold their concrete division to Denis Sullivan in 1989 and their timber supplies to Firth Industries - now Warkworth ITM - in 1987 to concentrate on their contracting and waste operations. In 1991 the company amalgamated with Ian Ward to form Transcon and take over Warkworth Transport.

Two years later, Masons went back on their own, returning to contracting and bulk haulage while Ian took over general freight and stock transport.

In 2013, Alastair decided it was time to downsize so split the business into two, Mason Containers and Mason Contractors. Alastair sold the Contracting business to current owner, Lance O’Callaghan.

Mason Contractors now has multiple branches in Warkworth and Kerikeri and covers the areas between, constructing small to significant infrastructure projects.
