Health and safety pre-qualification
Watercare utilses the Tōtika pre-qualification system we prefer all supplies undertaking construction works, maintenance and engineering services to be Tōtika qualified.
e-Tenders
We use e-tendering to simplify and speed up the tendering process. We publish our tenders on the NZ Government Electronic Tender Service (GETS). Registration is free.
As a registered supplier you can:
- Receive emails about our new public tenders
- Download tender documents
- Take part in forums to seek clarification of questions
- Upload responses to our tenders
Note: We generally do not provide hard-copy tender documents or accept hard-copy responses to tenders.
Unsolicited proposals
From time to time, suppliers may wish to approach us with a proposal to meet a perceived need, without being asked to do so. This is considered an unsolicited proposal.
We encourage suppliers to put forward good ideas, and we will treat these in a way that is transparent and fair to everyone.
We consider ideas that are:
- Unique
- Innovative
- Aligned with our plans, objectives and strategic priorities
- Detailed enough for us to assess their merit.
To submit a proposal, ask a question or learn more about our supply chain processes, please email [email protected]
Probity
Do you have a probity concern? Let us know.
We consider probity of utmost importance.
When conducting supply chain activities and at all stages throughout the procurement process, it is everyone's responsibility to ensure probity is upheld.
Any supplier who has a probity concern may contact our head of internal audit by emailing [email protected]
Alternatively, suppliers are welcome to use our confidential whistleblower service which is administered by PWC.
Click here to access the whistleblowing portal.
Alternatively phone or email PWC at 0800 177 792 and [email protected]
