Boyhood love of stream continues
Hadleigh Putt has fond memories of Po¯ kaiwhenua Stream — which is why he wants to save it.
South Waikato’s Po¯ kaiwhenua Stream is a special place full of memories for Hadleigh Putt. The Po¯kaiwhenua Catchment Group co-ordinator grew up on a dairy farm bordering the stream and says the waterway was central to family barbecues, fishing expeditions, camping, neighbourhood raft races, and general exploring.
“I’ve lived away from the area but, whenever I visit the stream at the back of the family farm, I feel connected to it, and to those places where so many memories were formed. In recent years I’ve been able to share these places with my wife and two boys, which is very special.”
The stream, which flows for 56km from near Tokoroa to Waikato River at Lake Karapiro’s eastern shore, has also served as a community hub, Putt says. “Cubs and Scout camps also took place beside the stream, and it was always a place we would take visitors to, and where we’d try to catch a trout or two.”
Now Putt and the other catchment group trustees are working in partnership with DairyNZ and the Raukawa Charitable Trust to protect the waterway. Their combined work to improve biodiversity and waterway health is currently focused on the Whakauru Stream, a stream tributary next to Tokoroa Sports Centre.
The project, which is funded by the Ministry for the Environment’s Jobs for Nature programme, brings western science and Ma¯tauranga Ma¯ori together to better understand ecological

health in waterways and how to improve it.
“In this early stage of the project, we are wanting to learn more about the Whakauru Stream, its history and what native plant and animal species live within and rely on it,” Putt says. “Freshwater ecology studies will help build this understanding, alongside Ma¯tauranga Maori methods.”
Ma¯tauranga Maori methods are based on cultural traditions, values and philosophies.
The partnership will also result in more than 15,000 new plants line the Whakauru Stream. Community and iwi planting days and pest and weed control activities are planned, and onfarm strategies to improve waterway health will be trialled and shared among farmers.
“A big component of this particular project is engaging with the community,” Putt says “We hope this work will provide a living example of what well-planned riparian planting can look like and be a source of inspiration for dairy farmers and the wider community.”
The catchment group has funding from Waikato River Authority for its work, enabling it to continue partnering with DairyNZ. Putt says this shows the authority’s increasing trust in what the group can do.
“It means we can boost the DairyNZ project and work with the Syben family on the other side of the Whakauru Stream. We now have a plan in place that will see the removal of pest weed species, refencing of the stream for the entire length on the edge of the Sybens’ property and planting of appropriate native species to form an effective riparian buffer.”
Catchment groups have proven to be effective in bringing communities together to achieve a common goal through sharing ideas and resources, Hadleigh says. He’s a firm believer in catchment groups’ ability to bring people together to achieve multiple environmental objectives.
His group was formed in 2021, after the idea of it came to founder Andrew Lennox. It has seven trustees — including Lennox, the group’s chair — and an email database comprising most of the catchment’s 250 landowners, as well as a Facebook page.
Putt became the group’s coordinator six months ago, after chairing the group since its inception. His past experience includes more than five years at Fonterra as a sustainable dairy adviser and 11 years with Ballance Agri-Nutrients. As coordinator, he organises the group’s various extension events, which involves connecting with host landowners and guest speakers in specialist fields. He also works with landowners around fencing and planting of riparian margins and other areas on farms best suited for retirement from grazing.
This work has helped change the catchment’s waterways over the years, he says.
“The biggest change I have seen is the huge effort farmers have put into fencing waterways to exclude stock, and the many great examples of riparian planting they’ve enthusiastically established in these fenced areas in the past 10-20 years.”
He hopes farmers within the catchment will continue the great work that has been started, to lessen their impact on the waterways within the catchment. “We would also like to see local residents enjoying the stream and taking on a guardianship role for it, and for the flora and fauna it supports.”
