Overview
The NZS3910 contract is one of the most commonly used construction contracts in New Zealand and is used on a wide range of projects from small scale residential and commercial projects through to complex infrastructure works. The recently updated NZS3910:2023 version was issued following a large scale and thorough consultation process across the industry and included amendments to cover the changing risk profile of the industry since the previous 2013 version.
Despite NZS3910 being widely used, there is still misunderstanding within the industry of the rights and obligations that the parties have under the contract, the importance of understanding and complying with the contract requirements (particularly the administrative requirements), how discrepancies between various contract documents are dealt with and the interplay with common law and statutory rights and obligations.
This masterclass will be based on the presenters’ extensive day to day experience of dealing with NZS3910 and matters that arise under the contract utilizing relevant practical examples and will provide an understanding of the key provisions in the NZS3910 contract, the key risk and common dispute areas, practical tips for managing performance under the contract and how to best position yourself if a dispute does arise.
