At peak production in the 1970’s the Penrose plant employed up to 600 employees at any one time. The types of asbestos used varied, however the most common was the white variety Chrysotile, which was cheaper and more easily worked. Another major use of asbestos in New Zealand was as the raw material for insulation and acoustic products.
Prior to the Second World War asbestos really only found its way into New Zealand in the form of manufactured items
The first was established in 1938 at Penrose in Auckland, by the Australian Company James Hardie Ltd. A second factory, operated by well known local company, Fletchers, was established in the Christchurch suburb of Riccarton in 1943. Asbestos was added because of its inherent properties high tensile strength, fibrous nature and heat resistance which provided reinforcing to the sheet material. The Auckland plant produced asbestos cement products until 1987 although from 1983 asbestos had been phased out of sheet products and was only included in pipes. At peak production in the 1970’s the Penrose plant employed up to 600 employees at any one time.
Estimates of the numbers employed over the life of the factory vary between 900 and and are confused by the fact that large numbers of casual workers were employed. The types of asbestos used varied, however the most common was the white variety Chrysotile, which was cheaper and more easily worked. Because the blue Crocidolite from South Africa was more expensive presumed better it tended to be used in only products requiring greater heat tolerance or strength such as in pipes expected to be subject to higher pressures or temperatures . Another major use of asbestos in New Zealand was as the raw material for insulation and acoustic products. This saw the various types of asbestos mixed with a binder and spayed around boilers, pipes, ducts and other places where insulation against heat and noise was needed.
From the 1950’s until the 1970’s thousands of tonnes of asbestos were applied in this way, most notably in the power stations built in the period, but also in railway workshops, shipyard buildings and maintenance and other large scale industrial applications. Usually the insulation was applied by contractors who mixed asbestos from the bags or sacks it had been imported in, before spraying the mixture on to chicken wire reinforcing. Usage increased dramatically during the 1960’s and until well into the 1970’s with the 500 tonnes being the minimum imported during that time and the average being closer to 800 tonnes. Chrysotile was sourced from a single mine near Takaka in the South Island from the early 1950’s until early 1960’s.
