Innovation

Kauri Park was awarded the contract having worked on other major infrastructure projects with the contractor and built up an excellent working relationship based on reliability and trust. Kauri Park understood the demands of a contract of this scale and the coordinated approach it took to deliver.

Planet & Eco-Leadership

The Te Rapa bypass was a mixture of roadside corridor plantings and swale gardens designed to mediate the storm water runoff from the motorway. Te Rapa has an exposed environment subject to harsh frosts and winds. Many of the plantings are at the same level as the road, meaning the plants selected have to tolerate carbon dioxide and road run off. The soil types are poor Waikato pea metal sands which lack nutrients and have minimal organic matter. Plant species had to be hardy enough to grow in poor soil.

A major focus on this project was the use of local ecologically sourced plants. Kauri Park were awarded the project in 2010 which gave time to source seed from local bush remnants in the Waikato district. This process went through scrutinized production involving both the contractor and consultants. Kauri Park was highly recommended by the consultants for its eco-sourcing and electronic tracking system.

Shared Success

This project has been a resounding success. The plants have established well and the Cortaderia in particular, are flowering profusely in the second year after planting. The swale areas planted in Schoenoplectus and Baumea are growing strongly and are mitigating road water pollution. There have been almost nil plant losses. The careful use of amenity plantings interspersed with reveg species will make this project a real eye catcher as it becomes more established.
