Our Urban Ngāhere

A decade-long mission to cool, connect and re-canopy South Auckland

This essay is made up of 15 photo montages. Click on the "view" icon in the top left of each to expand the montage and explore these photographs in detail. The captions provide an overview of the reasoning behind the programme, challenges for the trees and their communities, and the extraordinary climate benefits our urban ngāhere can bring.

In the spring of 2025, we invited Māngere photographer Anna Delany to document the Urban Ngāhere, particularly in the streets close to and bordering Ambury Park. In her images, full of contrast and tension, Anna’s lens asks us to imagine – and even have faith in – a future that may be slow to arrive. Her photographs, infused with patience and gravity, provide insight into the long-term project of growing trees and communities despite sometimes difficult conditions.

Urban Ngāhere is a 10-year tree planting programme, and 2024 is the first year of planting. It aims to reduce urban heat and increase flood protection, support biodiversity, capture carbon and improve the feel of our streets. Trees do all this and, once established, need little maintenance. The goal is to plant 80,000 large trees over 10 years.

South Auckland has fewer trees due to its development history. Built on cleared farmland, tree planting wasn’t prioritised as housing and industry expanded. The loss accelerated after 2015 law changes removed tree protections, especially in denser, lower-income areas. Auckland Council sees this is an equity issue and is restoring canopy cover where it’s needed most. While South Auckland is a priority, the programme is region-wide.

The urban ngāhere is vital cultural heritage. Remnants of native forest represent kai o te ngāhere (traditional supermarkets), wānanga o te ngāhere (learning centres), kapata rongoā (the medicine cabinet), kura o te ngāhere (schools) and wairua o te ngāhere (the spiritual domain).

Seen from above, tree canopy appears as a green patchwork covering streets, backyards and parks. The goal is to increase Auckland’s canopy from 15% to 30% by 2050.

The programme prioritises streets with no or only a few trees, as well as streets with schools, parks, lots of pedestrians or public transport routes along them. Highest priority areas are Māngere, Papatoetoe, Manurewa, Papakura and Franklin. The programme works closely with utility providers, so roots won’t interfere with power, water or telecommunications infrastructure.

Extreme heat is the fastest changing climate extreme worldwide. Even in cooler climates like New Zealand, we still have periods of relatively intense heat that can be hard to cope with. Street trees can cool a neighbourhood by up to 10°C.

Look for the stakes. The urban forest has a colour code. Pink = planted in 2024, red = 2025. The planting season is May to September (it should be April, but soils are staying drier for longer).

Specific trees are selected for each location, considering things like wind, salt and water. Sadly the trees can’t all be natives, which are vulnerable to pests and not always suited to street conditions. A mix of native, exotic and deciduous trees provide light in winter and shade in summer. Larger tree species offer more shade, soak up more rainfall and stormwater, store more carbon and help calm traffic.

The Urban Ngāhere programme is funded through the Long-Term Plan as well as targeted rates. Urban Ngāhere trees are monitored, weeded, pruned and fed for three years. As fast-growing trees, by three years old they’re robust enough to survive on their own.

Keeping trees in the ground is hard. Nearly one in three new trees don’t make it: they’re harmed or dug up intentionally. People might prefer parking on berms, dislike leaf litter, or want different species. Every tree lost costs, and means future streets will be less comfortable.

Data and strategy: In the past, street trees were planted in a reactive way. Now Urban Ngāhere uses data to plan for both local and regional canopies. The tech allows council staff and contractors to track every tree over time.

Landslides impact homes, infrastructure, roads and services and the effects of climate change can exacerbate these risks over time. The devastating landslides in and near Mauao, Mount Maunganui, are another stark reminder of the risk of landslides to life and property.
