Until now, one company's plasterboard has had a near-duopoly in New Zealand, leading to some of the highest prices in the world - 67% more expensive than the U.S. according to the Minister of Building and Construction.

The Government's introduction of a Building Product Specifications document will allow for greater competition in the market, and hopefully less costly building.
