(h) S. R. Irvine Limited

There is so much limestone in the County that there has always been competition to supply crushed lime. In the decade of the 1970's, three companies entered the market briefly. In 1971, S. R. Irvine Limited purchased the equipment of the defunct Tapawera Lime Co. Ltd. and set it up at the mouth of the Pearse River. In the three years to 1973, a total of 3151 tons were produced from stone won from slides in the Graham Valley, but the operation proved to be uneconomic and was abandoned.
