About McCallum Bros Ltd


Unloading red rock at  Motutapu

McCallum Bros Ltd is a family owned company, based in Auckland, which has been operating since 1904.

We are best known for supplying the red chip which gives the roads and suburbs of the Auckland Region their characteristic warm colours.

Our red aggregate is used for the distinctive exposed aggregate driveways and paving chosen by many home owners as well as the red concrete pavements in heritage areas of the city and sealing chip used for the shoulders of Auckland's motorways.

In addition McCallum Bros Ltd is a leading supplier of sand to the region's concrete manufacturers.

We supply a range of aggregates sand and shell to the building, roading, landscaping, sports turf and equestrian industries throughout the North Island and are also the leading contractors for the supply of beach replenishment sand in New Zealand.

Sand barge loading off Pakiri Beach

McCallum Bros Ltd have been extracting sand from the Pakiri area since the Second World War. The sand has always been in high demand due to its consistent high quality.

The grain size and freedom from silt and other contaminants makes it particularly suitable for ready-mix concrete manufacture.

We currently have two sources of sand which both originate from the Pakiri – Te Arai embayment. High quality sand from the near-shore source is used exclusively for the concrete industry while sand from the off-shore source is also used for other purposes such as beach replenishment.

Karamuramu Island Quarry

The quarry based on Karamuramu Island has been in operation since 1908. Karamuramu Island is located in the Hauraki Gulf aproximately three kilometres offshore from Kawakawa Bay.

The island consists of a red chert or jasper. Far from being a volcanic rock as many believe, chert is formed by sedimentary deposits being forced deep into the earth. This exposes them to extremely high temperatures and pressure which fuses the particles together into an extremely resilient and relatively lightweight rock.

The quarry has reserves of rock in excess of several million cubic metres but will not disappear. In order to preserve the profile of the island, extensive planting of the outer shell (using native plants) has been underway for some years now.
