Project Brief

The North Shore’s Tuff Crater, a volcanic crater known for its mangrove-filled salt marsh and stunning views of the Waitematā Harbour and Auckland skyline, underwent an upgrade to its walkway. Funded by the Kaipātiki Local Board, this project aimed to provide a safer, more accessible, and reliable experience for visitors. The upgraded walkway also plays a crucial role in connecting the wider Northcote area, addressing the needs of an increasing population and potentially linking to the future Northern Pathway.

Why BiForm was Specified

For the boardwalk’s construction, council staff opted for BiForm recycled plastic composite decking instead of traditional timber. This decision was based on several key factors:

  • Longevity and Durability: BiForm decking offers a longer lifespan compared to timber, significantly reducing the need for frequent maintenance and replacement.
  • Warranty: BiForm provides a 25-year warranty, ensuring long-term reliability and performance.
  • Cost Efficiency: The reduced maintenance and replacement costs associated with BiForm composite decking make it a cost-effective choice for the council.
  • Sustainability: Using recycled plastic, composite decking aligns with the council’s commitment to sustainable practices and environmental stewardship.

Conclusion

The upgraded Tuff Crater Walkway stands as a testament to the Kaipātiki Local Board’s dedication to enhancing community spaces. By choosing BiForm Solid Composite Decking, the council ensured a sustainable, durable, and cost-effective solution that will benefit the public for years to come. This project, supported by Forest & Bird and local mana whenua, exemplifies a successful collaboration focused on environmental conservation and community well-being.
