Current figures show that the demand for aggregate in New Zealand equates to eleven tonnes for every person annually. To fulfill this requirement a readily available supply of aggregate is essential.

Data retrieved from 50 years of geological information and site research means that Winstone Aggregates can forecast and schedule supply in excess of 30 years.

With the largest network of quarries and sand plants in New Zealand, we are able to plan distribution efficiently and have the ability to supply large volumes of stock at short notice.
