Construction Contracts Act adjudications

The Construction Contracts Act adjudication process provides a quick method of resolving construction contract disputes. Whether acting for property owners or contractors we understand the importance of presenting high quality expert evidence and legal submissions to support the adjudication claim or response.  We have the resources and industry contacts to act quickly and ensure the best possible case is presented on behalf of our clients.  We also advise on enforcement options.


Arbitration has proved to be a popular dispute resolution alternative to the Court process. It provides more confidentiality than Court proceedings, takes less time and enables the parties to choose an arbitrator with specialist expertise.  Grimshaw & Co has solicitors who are members of the Arbitrators and Mediators Institute of New Zealand (AMINZ) and we represent clients in construction dispute arbitrations. Our familiarity with arbitration ensures that we provide a high standard of advocacy on behalf of our clients in arbitral proceedings.
