Delivering Maritime Solutionsand Quality Aggregatesfor New ZealandersSince 1904

To ensure we can continue to support the upper North Island’s growth, we are undertaking a resource consenting process to allow extraction of sand at least 4.7 km off the coast of at Te Ākau Bream Bay to help meet the needs of the construction sector.

We know many Kiwis naturally have questions about the sand extraction process. Within this website we hope to demystify sand extraction and demonstrate that it can be undertaken in an environmentally responsible manner.

We are committed to providing as much information as possible throughout this consenting process. On this website you will find our application documents as they become available, background information and answers to many of the questions you might have.

Information on this consent is available here

Red chip gives a warm welcoming feeling to your home or business. The rich colour of McCallum’s red chip suits most colour schemes and landscaping products. It provides dynamic contrast to lighter colours and compliments darker tones. Red chip is a proven durable product that has been used for asphalt surfacing since the early 1900’s.

Red chip is an integral part of many Auckland landmarks, from central city buildings to walkways in the region’s parks.

Our Red Rock is exceptionally strong and offers excellent abrasion resistance.

The aggregate comes from McCallum’s Karamuramu Island Quarry situated in the Hauraki Gulf which is composed entirely of the stone chert or jasper.

Mike Haynes (Operations Manager) recently received the Trimble Outstanding Employee award for quarrying. The award was presented by Bruce Warner, Regional Manager Asia and Pacific for Trimble Loadrite.

Red Rock aggregates are sampled and batch tested on a regular basis and source property measures are taken as required.
