With origins in a former New Zealand government entity (the Ministry of Works and Development - established in 1885), Opus brings together the experience of more than a century of infrastructure development covering planning, design, project management, construction supervision, maintenance and rehabilitation.

In its transition from the Ministry of Works and Development to a fully privately owned company, in April 1988 Opus became the Consultancy Division of the State-Owned-Enterprise Works and Development Services Corporation NZ Limited.

Works Consultancy Services was sold to Kinta Kellas of Malaysia in November 1996 and as a result the company changed its name to Opus International Consultants Limited (Opus) in April 1997.

Opus’ international experience spans a period of over 50 years and has included over 100 projects in more than 20 countries. In 2002 Opus was recognised as the Trade & Enterprise New Zealand Services Exporter of the Year for its work in international markets and then again in 2006.  Opus was also named Trade New Zealand’s Supreme Exporter of the Year in 2006.

Our UK business was established in London in 1989. More recently and following mergers with Evans Grant Consultants, Veryards Consulting, Hastings Clements and Leach and Joynes Pike, Opus in the UK now operate from a network of seventeen offices.

In Australia Opus operates businesses in Western Australia (established in 2000), Queensland (also established in 2000) and Sydney (established in 2003) through a merger with Tierney and Partners.   All offices now operate as Opus International Consultants.  More recently, Opus acquired the large Australian based infrastructure consultancy Qantec McWilliam Consulting Engineers taking the number of Opus offices in Australia to twenty.

In Canada, Opus has offices in Fredericton (New Brunswick) and Victoria (British Columbia) and through a merger with Hamilton Consulting in Vancouver, Kelowna, Calgary and Detroit (USA). In May 2008, Opus acquired Project Engineering Ltd in Fredericton to combine with the present Opus Fredericton business.
