Natural Habitats / M2PP Alliance

Kauri Park Nurseries have been a pleasure to work with on the M2PP project.  Always courteous, the staff are also always willing to help and endeavour to make things run in most efficient way possible.  We look forward to working with Kauri Park Nurseries again soon.

The Mackays to Peka Peka Expressway is a key section of the Wellington Northern Corridor, a long needed upgrade of State Highway 1 north of Wellington. The 18km four-lane expressway has taken approximately four years to build, passes through Paraparaumu and Waikanae, including a new bridge over the Waikanae River. The new route is aimed to improve safety, reduce congestion and provide a more reliable journey time into and through the Kapiti Coast.

Kauri Parks role in this project was to supply the 1.2 million native plants required for the landscaping aspect. A very diverse list of species was required as a number of habitats were affected by the bypass, including sand dunes, coastal forest, riparian and wetland habitats. Plant supply included seed collection, seed propagation, plant growing and delivery to site. Kauri Park have worked very closely with a lot of parties over this period to ensure this part of the project ran smoothly.

Mackays to Peka Peka demanded a large amount of foresight, flexibility and capacity. Although the bulk of the planting was completed in 2015 and 2016, Kauri Park have been working on this project as far back as 2009. Delivery requirements to site are very high during the planting seasons, as many as 15,000 plants being delivered to site per day. Along with being in the industry for a long period of time and having an extensive track record, being able to fulfil these requirements made Kauri Park the natural choice for sole plant supplier on this project.

Planet & Eco-Leadership

To help protect the biodiversity of this unique region, the seeds for the M2PP project were all eco-sourced – seeds were sourced from plant material from the region which it was to be replanted back into, retaining the genetic footprint that has evolved over many generations.

In 2009 the M2PP Alliance contracted Boffa Miskell to plan and design the revegetation and planting mitigation works. As a result of a Boffa Miskell initiative, the Alliance agreed to undertake some initial seed collection and in early 2012 Kauri Park were awarded the contract for this work.  In 2012, the Alliance acted again on the recommendation of Boffa Miskell, to set up a planting substrate and plant species trial. This was established in August 2012, with Kauri Park supplying the plants for that trial. This provided useful information on soil mixes and the identification of the preferred species for the M2PP project.

For this project, enough collection points were secured to source most of the material in areas south of Himatangi. A number of challenges were faced collecting in this region, in particular, it was necessary to negotiate access to the best seed collection points which were either in private ownership, under local government or in DOC estate.

It took nearly two years of preparation in the build-up to the first collection year (2014). Working under strict guidelines, our first goal was to locate the species and secure enough collection sites to spread the load of seed collection over as many sites and individual plants as possible. We were fortunate to gain access to some of the most environmentally important and ecologically interesting sites in this region to achieve this.

Prior to the main collection, germination testing was undertaken of core species to check viability and check any evidence of cross pollination. As a result of this testing, a small number of collection points were ruled out.

We met many people during our time collecting in this region, who are passionate about this project and what Kauri Park did with eco sourcing. These people understood the significance of this planting and the importance of getting it right.

We would like to extend our special thanks to all the private land owners, Nga Manu Wildlife Reserve, local government, local iwi and DOC for granting Kauri Park permission to access some of the most amazing ecologically diverse areas in the Foxton Ecological District. Without their permission and understanding of environmental issues, we would not have been able to undertake this collection.

Shared Success

Mackays to Peka Peka has been an astounding success, with a 98% plant survival. The plants have established extremely well, exceeding even our own expectations.

This project is the largest NZTA contract we have worked with to date, and are pleased to have been the sole plant supplier working alongside the Landscaping contractors Natural Habitats.
