While the overflow has stopped, our teams are working to clear a blockage which still remains. They are working at pace to identify the blockage and get this cleared. 

One southbound lane clasure remains in place approaching Ngauranga while work is underway.

What we need

Wellington Water Limited is initiating a request for proposal (RFP) to implement several core technology systems under its Technology Systems Investment (TSI) Programme. The TSI programme addresses urgent system gaps resulting from deferred investments and evolving operational needs and supports the needs of the potential new water services entity planned under the Government’s “Local Water Done Well” policy. The systems (each known as a Tower) in scope of this RFP include:

  • Programme & Project Management (PPM)
  • Health & Safety System (H&S)
  • Asset Management Information System (AMIS)
  • Financial Management Information System (FMIS) and Supply Chain Management
  • Customer Relationship Management System (CRM)
  • Billing System (Billing)
  • Human Resources Information System (HRIS) 
  • Payroll

 

Participants can respond to one, some or all these Towers.  

The full scope of the TSI Programme also includes information management, this is being managed via a separate RFP.

The coloured boxes in the diagram below highlight the system areas of the RFP and correspond to the capability model areas.
