Located near Christchurch, on an old Waimakariri River channel, Yaldhurst Quarry is perfectly positioned to produce the highest grade greywacke products. An accredited Christchurch City Council facility, the site manufactures a range of aggregates and sand for use in ready mixed concrete, concrete products and other building, civil engineering and roading projects.

Recently, Yaldhurst Quarry has undergone some major changes. While a weighbridge and new office has been installed and commissioned, a number of new initiatives have seen alterations to the way the site is operated.

Upgrades to the excavation fleet have included the replacement of two old Komatsu HD200 dumpers with a larger, more reliable CAT 769. The switch from two machines to one machine has provided increased efficiencies in the load and cart area as well as quicker cycle times (saving fuel), reduction in repairs, maintenance and servicing costs.

The fixed plant, set up to produce a range of natural round and crushed concrete aggregates and sands, has seen an Englishmade Kue-Ken 30 x 12 jaw crusher introduced into the circuit to crush the 80mm to 140mm boulders – they’re then fed back into the cone to increase crushed sand and aggregate production. This change in methodology has seen an increase of around 15% throughput of the crushed material with the biggest boost in the daily PAP volumes produced.


In the late 1800s, development in the Christchurch and the mid-Canterbury area created a high demand on gravels and the mainstay supply was the Waimakariri River. But although the river had a plentiful supply of gravel, there were disadvantages: weather and flooding impacted extraction and pressure surrounded the industry as the sustainability of continued gravel extraction became questionable.

As Christchurch grew and with it the demand for aggregates, the distance from markets increased, and transport costs became inflated. An alternative supply was sought and the region saw the introduction of land-based pits.

The site Yaldhurst Quarry occupies had been used for farming and cropping before being developed as a land based quarry in the early. Known as the Yaldhurst Gravel Pit, the operation supplied aggregate and sand for concrete manufacture in the mid-Canterbury area.

In 1996 the original fixed plant was decommissioned on account of the close proximity to its neighbours, and the growing distance between the extraction face and the processing plant. A new, portable plant was developed: a kitset form allowed the plant to be moved to follow the material face. In 1999 the plant was located very near the gravel face ensuring a very efficient operation. But, over time, the semi-portable concept has been outweighed by the costs associated with relocating the plant and services around the site.

Today, the plant has become a fixed process and is likely to remain in its current location until the end of the resource.
