Contractors / Health & Safety / Prequalification With Wellington Water

Prequalification with Wellington Water

Before a contractor starts working with us, we want to know they are a safe company that has good systems, capability, and is backed by credible evidence. Prequal is one of the first steps for selecting good contractors. 

Prequalifying safe and good contractors are major steps of the Principal's Guide to Contracting to meet Health and Safety Legislation.

Wellington Water requires all contractors and consultants to meet the Tōtika prequalification scheme standard. Tōtika is overseen by the Construction Health and Safety Association of New Zealand (CHASNZ). Tōtika recognises Safe365, Impac, and SHE PRE-Qual pre-qualification assessments, with more likely to be added in future. CHASNZ has more information.

Contractors engaging sub-contractors must have systems in place to ensure they are controlling the risk that sub-contractors may bring to work. This could include their own internal prequalification or requiring an external prequalification (e.g., Tōtika, SiteWise, Impac, ISO45001). Sub-contractors that are prequalified directly with Wellington Water (through Tōtika or through Fulton Hogan) can be considered prequalified for use by other contractors.  

Contact the Wellington Water Health and Safety Team to determine if a sub-contractor is already prequalified. All contractors must ensure processes are in place to ensure sub-contractors are meeting the Wellington Water Standards while working for them.
