Poroti is a small rural settlement in Whangārei District, set along Mangakahia Road in farming country west of the city. Its name belongs with the Poroti Springs, where water from Whatitiri rises as Waipao Stream, a source local hapū have cared for over generations and that still helps supply drinking water to Whangārei. This is not a township with a shopping street.
The markers of the place are the springs, Maungarongo Marae beside the road, and Poroti School. Around them is working farmland. Anyone passing through is on a public road next to a water supply and a Māori reservation, not at a park or a beach.

About Poroti
Poroti sits at the foot of Whatitiri, a volcanic cone that rises out of the surrounding farmland. A research report filed for the Waitangi Tribunal records the maunga at 347 metres and describes groundwater leaving its slopes to emerge in a series of springs at the head of Waipao Stream.
The stream flows toward the Wairua River. The head spring and the land immediately around it are a Māori reservation.
The settlement itself is a loose rural community rather than a village centre. Mangakahia Road is the spine. Farms occupy the country around the maunga, and the public institutions are few: a primary school, a marae, and the water infrastructure that takes spring water toward the wider district. There is no verified shopping strip, hall listing or passenger transport stop to anchor a town visit.
Poroti School is the everyday focus for local children. It is a state coeducational full primary, teaching years 1 to 8, at 673 Mangakahia Road. The school held a 125-year reunion in 2004, so it has been part of this community for a long time. Secondary schooling is outside the settlement.
Maungarongo Marae stands on the southern side of Mangakahia Road, close to the springhead. That pairing, marae and spring, is the cultural centre of Poroti.
The wider story is about who may take the water, and how a rural reserve came to supply a city. That history is still being worked through between the trust that cares for the springs and Whangarei District Council.
Poroti Springs and the Water Supply
The Whatitiri Māori Reserves Trust administers the Poroti Springs for hapū members of Te Uriroroi, Te Parawhau and Te Māhurehure ki Whatitiri. The Waitangi Tribunal research describes the springs as a mahinga kai, a place for watercress, kewai (freshwater crayfish) and tuna (eels), and as water used in ritual as well as for daily life.
For decades the permitted take was fully allocated away from the landowners. Whangarei District Council has said the springs supplied about 30 percent of the city’s water, with a further take held by the Maungatapere Water Company for irrigation.
Hapū and whānau who owned the spring land, and who had looked after it for generations, could not secure a take of their own.
In 2025 the council and the trust signed an agreement to share part of the council’s raw-water allocation from Waipao Stream.
Under that decision the trust has first rights to the first 2,000 cubic metres of the council’s daily allocation of 15,500 cubic metres, and may take a further 3,000 cubic metres a day when the council is not using that water.
The agreement was tied to a major upgrade of the Poroti Water Treatment Plant, described by the council as a $45 million project, so water from the Wairua River can also be treated there.
The plant already treats water from the Poroti Spring and distributes drinking water to residents and businesses in Poroti and Maungatapere, and to parts of Raumanga and Maunu, including the hospital.
Council project notes say the upgrade is meant to handle sediment washed in during heavy rain, and to give Whangārei more drought resilience by adding the Wairua River as a source the plant can treat. Northland Regional Council remains the body that allocates how much water may be taken.
Visiting the Settlement
Poroti is a place people live, not a developed visitor site. Mangakahia Road is public. The school is a working school. The springhead land is a Māori reservation managed by the Whatitiri Māori Reserves Trust. Council material does not present the springs as a swimming spot, picnic reserve or walking track.
If you are driving through, stay on the public road unless you have been invited onto reservation land or a private farm. Do not treat tanks, bores or the treatment plant as a lookout. The water here is a living supply and a cultural site. For a longer shop, a supermarket or most other services, continue to a larger centre.
