Wairākei landscape plan

Until 1910, the Wairākei Stream headwaters flowed down from Pāpāmoa Hills and Otawa. The headwaters merged with the dune wetlands of Omanu and Pāpāmoa, west of Domain Road. The Omanu and Pāpāmoa wetlands (low lying swamps between dune ridges, still visible today on undeveloped land) extended for kilometres between Omanu and the Kaituna River. The Wairākei Stream flowed east towards the Kaituna River, before turning west again and flowing out to sea at the Taylor Reserve estuary.

The Wairākei was a tidal river and navigable, with people travelling by waka to and from pā in the vast wetlands and dune plains. The Wairākei river was fringed with raupo and manuka and contained an abundance of fish, which could be seen from the banks in the clear water.

By the early 1800s flax became a commodity for trade. Land was drained and large-scale planting and harvesting supplied at least two flax mills near the Wairākei Stream and Kaituna River. Later that century swampland was converted to farmland.

From the late 1800s, the wetlands were managed by Land Drainage Boards. When the East Coast Main Trunk railway line was constructed in 1910, the Wairākei Stream’s headwaters were diverted and the stream mouth silted up causing flooding. To drain the wetlands and lower groundwater, Harrisons Cut artificial outlet was excavated in the early 1940s. By the 1960s, the Wairākei Stream estuary was filled in and a second artificial outlet installed (Grant Place weir) to continue to maintain lower groundwater levels and drain stormwater.

Tauranga City Council is enhancing sections of the Wairākei Stream reserve to implement the Te Ara o Wairākei landscape and cultural management plans. We’ve consulted with the public and heard your aspirations for the Wairākei Stream corridor and are looking to address these while fulfilling the agreed plans as required by the BOPRC issued resource consent.

The landscape plan is a condition of Council’s comprehensive stormwater consent for Pāpāmoa and is designed to enhance the 15-kilometre-long stormwater reserve between Pacific View Road in Pāpāmoa and the Te Tumu boundary, including Taylor Reserve, encouraging people’s use and enjoyment of the area.

The intent is to protect and enhance ecological and cultural values, including the planting of an estimated 500,000 native plants along the stream margins.

Besides managing stormwater, the reserve will include more walkways and cycling routes. It will also express the heritage and cultural significance that the area has for Tangata Whenua, through cultural art, signage and traditional practices in the reserve.

Public consultation happened at the start of the project, and community feedback has been integrated into the design. 

Work will be completed in two stages. Through to the end of 2025, work on stage one will be taking place through the Wairākei area, including the landward side of the Wairākei Stream from Pacific View Road through to Golden Sands Drive.

Work on stage two will be taking place through the Te Tumu area. This area encompasses the rural zoned land from the eastern end of Pāpāmoa Beach Road, eastward to the Kaituna River. Plans for this area will be further developed following rezoning.

As part of the plan, 15 kilometres of the Wairākei stormwater reserve will be enhanced with new plants, landscaping, park furniture, signage and upgrades to the existing amenities. 
This includes: 

• 11km of new cycleways and pathways - a series of bridges, cycleways, pathways, and boardwalks have been installed along the reserve and walkways widened to allow for shared use.  
• 25 hectares of vegetation enhancement - this includes trimming, crown lifting and removal of vegetation in some areas to improve safety, creation of 51 sediment retention wetlands, wetland and shrub planting, and park benches to sit and relax.
• New signage - signage identifying exits, roads, and wayfinding within the reserve will be installed, as well as special signs that recognise places of cultural and historical importance.

Throughout the year, certain phases of the work will require the use of machinery to undertake the landscape works. Disruption to residential areas is expected to be minimal, and each stage of work will progress quickly.

• Of the 919 survey respondents, 34% think planting along the entire corridor is a good idea, 16% think it’s good but want to exclude ponds/Palm Beach West and 20% don’t think planting anywhere is good. Of the group that say yes, 3% live in Palm Beach West.
• An additional 28% of respondents didn’t choose yes or no, but selected ‘other’. Of this group, 64% say yes to planting conditional to suggestions such as ‘not in certain areas’ or have more specific requests.

We are aware of some misinformation about the objectives of this project published on signs in the reserve and a related website. The information provided on the website mixes opinion with fact which isn’t in everybody’s interest. To ensure the community receives facts, we list a few key ones about planting:

• Benefits of riparian planting are scientifically proven, they form part of the national drive to improve freshwater quality and address some of the very issues people in the area are concerned about, most importantly the quality of the water and stabilising banks.
• Short growing natives have been chosen to retain water views.
• Riparian planting will also improve biodiversity, by reducing water temperature and improving habitat for native resident species.
• Planting is a fundamental part of the landscape and cultural management plans for the stormwater reserve.
• The reserve is council owned land that forms part of a stormwater network managed for the benefit of the wider community. It is available for public use and enjoyment under the specific requirements of a resource consent.
