W-Squared was recommended to us in late 2014 when seeking advice on specific construction legislation. On a number of occasions since then, we have sought a number of services W-Squared are able to provide, ranging from preparation of documents for product approval such as Codemark through to determinations on NZBC clauses.

In every instance, we have found Bill Wright to be professional, honest and vastly knowledgeable about any compliance to the NZBC.

We would have no hesitation in recommending Bill and his team.

I have dealt with Bill for many years in a professional capacity both in his time with Auckland City Council and in private practice and have always found him to be very professional, very knowledgeable and practical in his approach to all situations. He has a strong understanding of the construction industry as a whole which allows for a holistic approach to both design and project management. I would have no hesitation in recommending Bill to any prospective clients looking to utilize his services.
