Steven C Evans

He joined CMC Asia Pacific (later, Concordia) in 2016 to assist in the company’s expansion throughout the Asia Pacific region.

Steven’s experience encompasses a wide range of market sectors, construction types and methods, covering disciplines such as quantity surveying, commercial management, project management, claim preparation and defence, adjudication, arbitration, mediation, contract drafting and vetting and training.

Raine Selles


Raine has been working in the construction industry since the age of 17 and has built a career around the resolution of complex construction disputes internationally. In 2013, she founded CMC Asia Pacific (later, Concordia), and in a short time, have developed it into a professional and well-respected organisation within the region.

She has helped settle more than 800 disputes and has achieved settlements of more than $5bn in New Zealand and Australia.

Raine practices as an Expert Witness, Adjudicator, Mediator and Arbitrator but her main focus is on facilitating the parties to reach agreement without the need to invoke formal processes.

Her background in quantity surveying and commercial/project management and being qualified in law pays dividends in having construction knowledge that lawyers do not.

Raine is NZ’s leading authority on NZ3910:2013 and has trained Stakeholders across all disciplines for almost 10 years. She also regularly lectures on Contract Law, Adjudication under the CCA, NEC 4 and more.
