We believe there are two potential groupings under this option.
Palmerston North City Council, Whanganui District Council, Ruapehu District Council and Rangitīkei District Council
Whanganui, Ruapehu, and Rangitīkei District Councils are looking at forming a water organisation together. As of the date our consultation document was adopted, all three had stated on their websites that they would also consult on an option that includes working with other councils within the Horizons Regional Council area. We haven’t had specific discussions about a water organisation involving all four of us, but since we are all considering a regional model as an option, it remains a possibility. There has been some indicative modelling of potential costs for all councils within this wider region.
Whanganui has a larger population and well-established water infrastructure, meaning this option could include two major urban areas. This can help manage costs by having more water connections per kilometre of pipe.
This grouping does, however, present some challenges due to the distance between our councils. This could make it harder to create efficiencies in areas such as operational centres, staff coverage, and equipment storage.
While we’re all within the Horizons Regional Council boundary, Palmerston North isn't neighbours with the other three councils. This means we don’t know each other as well as Horowhenua and Manawatū District Councils. Not sharing a boundary between us could provide a challenge in an emergency response. If there was a need for a particular piece of equipment or specialist staff member, the response could be delayed due to travel times between boundaries. Under this grouping, there are a number of combinations that could work to meet government requirements.
Palmerston North City Council, Horowhenua District Council and Manawatū District Council
Our three councils are part of Option 1, along with Kāpiti, showing that we're open to working together in the future. Manawatū and Horowhenua have decided not to join a full regional model but are still considering smaller partnerships, as seen in Option 1.
Under this option, we could collaborate with all three councils, just one other council – or together join with some of the other councils in the cluster above.
An advantage to working with Manawatū and Horowhenua is that our councils and communities are closely connected—people often cross boundaries for work, visiting family and friends, or leisure. In a civil defence response, we have alternate routes to access each other too. Being geographically close means we could achieve some efficiencies, but the savings wouldn't be as significant as if we partnered with a council that had a larger population to help share the costs.
A couple of councils are not included in potential combinations
Option 1 includes Kāpiti Coast District Council. As they’re not in the Horizons Regional Council boundary, we haven’t included them in Option 2.
Tararua District Council sits within the Horizons Regional Council boundary. However, in December, it voted to exit any further discussions regarding a regional water organisation. It is only consulting on its status quo, and a collaboration with Wairarapa Councils. As it has not signalled an interest in working with any councils in the regional boundary, it is not included in this option.
If either council (Kāpiti or Tararua) had a desire to join a water organisation with councils named in this option, we would be open to that.
We also haven’t looked at the two mini clusters combined. That’s because Horowhenua and Manawatū District Councils ruled out a full regional model, so we don’t know what their appetite may be for joining with Whanganui, Rangitīkei or Ruapehu. We would be open to working with all five of these councils if they desired.
If you’re wondering why some councils in the region have signalled they don’t want a full regional model, the main reasons are a desire to work with their immediate neighbours, within a catchment, or that they are considering a single council water organisation.

Notes about this map:
- Palmerston North City Council is open to collaborating with other councils.
- Horowhenua and Manawatū District Councils aren't consulting on a full regional model but through option 1 have indicated an interest in working with us and some other councils.
- Whanganui, Ruapehu and Rangitīkei District Councils have indicated they're likely to consult on working with other councils in this region. However, it's not their preferred option.
- Tararua District Council is not consulting on an option involving councils in this region.
