Principals and main contractors

SiteWise is an online prequalification system that grades your contractor’s health and safety capability and publishes that grade in a database which you can view.


How does SiteWise work?

You will be able to use SiteWise to make better – informed contractor selections, making the tendering process more simple and efficient. Contractors complete a 12 step questionnaire, which is assessed by our qualified team of health and safety practitioners. This results in a percentage score which is published in the SiteWise contractor database, and can be accessed by main contractors or principal organisations who have signed up to use SiteWise.

This prequalification database was created in response to the influx of contractors and subcontractors into Christchurch after the Canterbury earthquakes. After success in Canterbury the system was rolled out nationwide and now sees a large number of principals organisations using the tool to enable them to:

  • View all tendering contractor prequalification results in one place
  • Create shortlists based on health and safety assessment results
  • View contractor health and safety performance across different worksites

Backed by Site Safe

SiteWise is brought to you by Site Safe New Zealand. A not-for-profit organisation, Site Safe is committed to creating a culture of safety in the New Zealand construction and related industries. As experts in both health and safety training and delivery, we work with businesses to raise the bar in health and safety performance. We want everyone to go home healthy and safe at the end of each day.

“We have found that having our higher-risk contractors Sitewise pre-qualified has been useful in creating a level playing field, providing a clear and basic safety measure to achieve. It is part of lifting the safety standards in Northland and along with our other fellow Northland-based councils, who have also gone down this same track, it has resulted in local contractors only needing one pre-qual requirement.”

“It has given us a great deal more visibility as to contractors’ health and safety performance and commitment, and has also been a helpful tool to communicate what good practice in health and safety looks like.”

Charlotte Browne

Health and Safety Advisor, Waimakariri District Council

“We thought it was the best thing to do for the company, and our contractors. With hundreds of contractors now signed up, it has turned into a really positive thing for us.”

Rebecca Gornall

Group Health and Safety Manager, Mike Greer Homes

“As part of an effort to lead the way in contractor management and prequalification, the Central Otago District Council (CODC) joined the SiteWise prequalification system in 2015. CODC’s participation in SiteWise has been a positive step in reinforcing effective health and safety systems. The Council continues to use SiteWise to make informed contractor selections to ensure that health and safety considerations, at all stages (from design through to implementation) of a project or contract, are given significant weight.”
