The Halo Project brings communities together to restore wetlands, protect coastal habitats, and support native biodiversity in Ōtepoti Dunedin.

Protecting biodiversity from source to sea

The Halo Project started in 2009. It works to protect native species in and around the Orokonui Ecosanctuary near Dunedin. Today, the project supports predator control and ecological restoration, from inland headlands to the coast.

Staff and volunteers work across public and private land. They plant native species and restore habitats.

Project lead Rhys Miller says, “We’ve taken quite a strong focus on riparian and wetland areas, but also we’re starting to focus on the likes of headlands, particularly where they might provide habitat for some of our coastal bird species.”

A community-led approach

The project is built on strong community support. For example: 

  • the Halo team uses a repurposed pig shed, donated by a farmer, as a nursery
  • local tradespeople set up irrigation
  • volunteers came together for planting days – fuelled by fish and chips.

Rhys says, “The Halo Project has set up a really well functioning – but number-eight-wire – nursery system that is able to lower the cost of plant production.”

This low-cost nursery model helps the team grow stronger, more resilient plants by raising them on-site before planting. These plants are better adapted to local conditions, making them more likely to survive and thrive.

Restoring wetlands to reduce flood risk

At Wharewerawera (Long Beach), Halo is restoring an ephemeral wetland that helps protect nearby communities from flooding. An ephemeral wetland is one that’s only wet during certain seasons. When healthy, wetlands slow water during storms, reducing the risk of flood damage.

Planting at this site considers both environmental and cultural values. The team works with Heritage New Zealand to avoid disturbing archaeological remnants left by early Māori.

Volunteers, landowners, and staff use an Accidental Discovery Protocol. If anything is uncovered during planting, it can be protected.

Alice Macklow, Source to Sea Project Manager for the Halo Project, says, “One of the ways at Long Beach that we mitigate for the risk of harming archaeological remnants is not using an auger. So, we use shovels, and our volunteers know what to look out for in case they see anything.”

Planting smarter: Working with nature

The team uses smart planting techniques to improve success rates. They work with what already exists. They add to patches of native vegetation instead of planting whole areas.

This creates natural shelter from wind and weather, especially important on exposed coastal sites.

In earlier years, clearing pest plants exposed seedlings to wind damage. Now, the team leaves some pest plants in place to act as shelter. These are removed later once the new plants are well established.

Long-term goals for people and nature

The team hopes to restore ecosystems where native species and people thrive together. One goal is to improve water quality, so people can safely gather kai like cockles from local bays.

More birds are returning to the area. Rhys often sees or hears kererū. He’s even swooped by them on his driveway.

The project’s ultimate goal is to make living alongside thriving native species a part of everyday life.

“I get bombed walking down my driveway every morning by kererū, which is fun, and I love it,” Rhys says. “It would be fantastic if everyone in this area, in the city, up and down the country had that same experience. So, we’re living in amongst nature in a more normalised way.”

Learnings from the Halo Project

  • Use existing native vegetation to provide shelter and improve planting success.
  • Leave some pest plants in place during early planting to protect seedlings.
  • Build local support by involving community members and using local resources.
  • Train volunteers to recognise and protect cultural heritage.
  • Protect seedlings from pests and weeds using simple, low-cost methods.
