Protecting New Zealand's Waterways

Riparian planting is the establishment of native vegetation alongside streams, rivers, lakes and wetlands. It is one of the most effective ways to improve water quality, reduce erosion and create habitat for native wildlife.

At Orari Nursery, we've supplied native plants for riparian projects across Canterbury and throughout New Zealand, from small lifestyle blocks to large-scale environmental restoration.

Benefits of Riparian Planting

• Stabilises stream banks and reduces erosion.
• Filters sediment and nutrients before they reach waterways.
• Improves water quality.
• Provides shade that helps regulate water temperature.
• Creates habitat for native birds, fish and insects.
• Enhances biodiversity and strengthens natural ecosystems.

Choosing the Right Plants

The best species depend on your site conditions, including soil type, moisture levels and exposure.

Common riparian species include:

• Carex secta
• Carex virgata
• Mānuka
• Kānuka
• Harakeke (New Zealand flax)
• Tī kōuka (cabbage tree)
• Tōtara (where appropriate)

Our team can help you choose the right plants for your project.

Planning Your Project

Successful riparian planting starts with good planning.

Consider:

• Site preparation and weed control.
• Plant spacing.
• Protection from stock.
• Ongoing maintenance during establishment.

If you're planning a larger restoration project, we're happy to provide advice on suitable species and planting requirements.
