Independent Accreditation New Zealand (IANZ) asked NZIER to describe and quantify their role in supporting New Zealand's economy. IANZ accreditation provides New Zealand firms with an independent 'seal of approval', which reduces transaction costs and risks, especially for exporters. IANZ supports industries that account for almost 360,000 jobs, $28 billion of exports and $36 billion of GDP. We also used Computable General Equilibrium modelling to illustrate the economic benefits of the price premium that accreditation gives New Zealand exporters – some $2.4 billion.
