State highway professional services contract proforma manual

A manual for use by the NZ Transport Agency, Transport Services team when preparing tender documents for professional services contracts.

Z Series - minimum standards

The NZ Transport Agency Z Series of minimum standards covers a range of topics in the table of links to documents below. 


The NZ Transport Agency health and safety related documents Z/5 and Z/13 and its associated links are now out of date and do not align to current good practice in contractor health and safety management.

Health and safety management should be a shared responsibility, with a greater need for the Transport Agency to lead its downstream contractors in working together to manage risk.

The Contractor health and safety expectations document forms part of a wider contractor management process currently being developed that encourages downstream contractors to take ownership for risks to health and safety, work with other contractors to manage risk. It also empowers them to use innovation, their experience and knowledge when managing these risks.

Note: The Transport Agency Contractor health and safety expectations will replace Z5, Z13, the Zero Harm portal and all previous Zero Harm related health and safety minimum standards. All other Z documents remain in effect.
