The 170ha Roydon quarry 15 km west of Christchurch was identified as a suitable replacement for Fulton Hogan’s Pound Road quarry in 2010. Consent applications were lodged in 2018, and consent received from the Environment Court in November 2021 after an extensive community consultation process, with more than 200 conditions relating to the quarry’s development and operation. Development commenced in April 2022 and the quarry will be operational in 2024. The quarry contains an estimated 30 million m3 of aggregate and has an expected life of up to 30+ years.
Selwyn District council and Environment Canterbury are the two councils with regulatory functions for the site.
As it will be part of the local community for a considerable time, the quarry is being developed with the best systems, technology and practices. One of the first steps has been moving 500,000m3 of site gravels and soils to build a 5.5km bund around the site, and planting this with native plants. Minimising energy use in the quarrying and by customers is a priority, leading to, for example, a redesigned access and ring road to save more than 45,000 truck km travelled per year (at the consented maximum of 600 trucks entering and exiting per day). Loader numbers and travel is also being reduced by the use of telescopic radial stackers and relocatable field conveyors.
Fulton Hogan’s newest large scale alluvial quarry, Roydon benefits from the latest air quality monitoring technology. Three mobile monitoring facilities are linked to a central, certified, reference monitor, ensuring accurate measurement site-wide. Information on air quality is received constantly, allowing the quarry operation team to respond should air quality (dust) levels begin to rise. This technology has benefited from learnings at other Fulton Hogan quarries.
Air quality is also protected by a limit of 26 ha of open areas for the operation of the site at any one time. The area of physical extraction at any one time will be limited to 5ha. Other mitigation measures include the sealing of roadways, using conveyors to move material (rather than trucks) and applying water through foggers and misters as conditions require

At all times: (Dust suppression, operation of weighbridge, office activities, site security and light maintenance as required.)
Fulton Hogan manages the quarry to confine dust to the quarry site, using the latest dust mitigation measurement technology. This includes three mobile monitoring facilities linked to a central, certified, reference monitor. This ensures dust can be measured across the site, and the central monitor ensures the accuracy of all three mobile monitors. Information on air quality is received constantly, allowing the quarry operation team to respond as necessary to significant changes. The hourly and daily averages are recorded and made available to the public.
Weather monitors on and off site ensure that if extremely high winds are predicted, the quarry can be managed and activities adjusted depending on what the weather information shows. Key dust minimisation measures are:
- mobile monitoring stations linked to a central reference monitor
- limiting the area open for extraction at any one time to a maximum of 5 ha
- sealing all main roadways
- using field conveyors to move material
- using foggers and misters
The Roydon site has high quality aggregate resource, relatively few neighbours and good access directly onto Main South Road and State Highway 1.
Given that aggregates are a vital component in everything from roads, cycleways and railways to water networks and housing, the further that aggregate needs to be trucked, the higher the financial and environmental cost for the community. The quarry is in one of the fastest growing districts in New Zealand, and near a city that has had considerably higher-than-usual demand for aggregate as a result of the earthquake rebuild needs. It is a direct replacement for Fulton Hogan’s existing Pound Road Quarry, which will reach the end of its life mid this decade. The Pound Road Quarry has operated alongside the Templeton, Islington and Hei Hei communities for the past 30 years.
The protection of Canterbury’s groundwater is of the utmost importance, reflected in the consent conditions from Environment Canterbury and Selwyn District Council for the quarry’s operation.
Even though Roydon Quarry is outside Christchurch’s Groundwater Protection Zone, excavation is undertaken to no less than 1m above the seasonal high groundwater level on the site. Backfill is cleanfill only, and ongoing water quality testing assesses any changes in groundwater quality.
The health and safety of our people and locals is of paramount importance, and has been central to the design of the quarry’s operating systems. Our consent requires that we undertake 12 months of testing of RCS (Respirable Crystalline Silica) upon the site becoming fully operational (late 2024) which will be carried out over two summers.
The quarry is being excavated in sections or stages, beginning in the centre of the site and moving thereafter toward Dawsons Road and, in stages, toward Jones Road. Quarried parts of the site will be rehabilitated during the quarry’s lifetime, and no more than 10ha will be used for extraction and rehabilitation at any one time.
A condition of the consent is that Fulton Hogan will rehabilitate the proposed Roydon Quarry and make it fit for another designated purpose. Most of the remediation will be undertaken while the quarry is still operating, made possible by the staged approached to the quarry operation, reinstating, as far as practicable, the productive capacity of the soils.
The quarry is for Fulton Hogan’s commercial customers only.
