Expansion proposal
We’re proposing to gradually expand the existing Clevedon Quarry to secure aggregate supply for future infrastructure projects and developments in Auckland.
As Auckland is expected to continuing growing, with an estimated population of 2.8 million by 2048, demand for aggregate will continue to increase. As aggregate is a necessary component for all types of development, including roading and housing, ensuring sustainable extraction is secured in the long term is key to supporting this local growth.
We’re proposing to expand the existing Clevedon Quarry within the site to provide secure aggregate supply for the growing demand for future infrastructure projects and developments in Auckland.
We’ve identified a section of our current site that can be gradually expanded for extraction for the next 50 years without significantly increasing traffic movements in the local area.
Overview of the proposed expansion
In 2018, resource consent was approved to expand Clevedon Quarry over a total area of 29 hectares, with the ability to extract up to 3 million tonne (MT) of aggregate a year.
To meet the increasing needs of a growing market and to operate more efficiently on the site, we’re proposing to expand the Clevedon Quarry further.
-
The 35-year consented life of the quarry will extend to 50 years in total.
-
There will be no increase in the consented number of truck movements along local roads.
-
The consented extraction limit of 3 MT will remain and not increase.
-
The total size of the quarry will expand within the Stevenson landholdings but not into any neighbouring properties.
-
Extensive planting will be undertaken throughout the site and along the riparian margins of retained streams to off-set ecological loss.
-
A new wetland water treatment system will be constructed to manage runoff from the quarry before it enters the Wairoa River.

Clevedon Quarry connects with local community

The events offered locals, whānau, nearby neighbours and the wider community the opportunity to see the quarry up close and learn more about what’s planned for the future. Stevenson […]
