The Government is praising 25 years of global action that is fixing the ozone hole.
Environment Minister Amy Adams said the ozone layer was now on track to full recovery within this century, thanks to the Montreal Protocol, which phased out the production and use of ozone-depleting chemicals.
"New Zealand is proud of its role at the forefront of action to phase out ozone-depleting substances. We were one of the countries pushing for a strong agreement on this issue, and we signed the Montreal Protocol on the first day it opened for signature on September 16, 1987."
A good example was the Government-accredited Refrigerant Recovery Trust scheme, which had collected and disposed of 47 tonnes of refrigerants since 2010. This represented a saving of 63,000 tonnes of ozone, Ms Adams said.
"We are on track to completely phase out imports of hydrochlorofluorocarbons - the final ozone-depleting substances under the protocol requiring action by New Zealand - by 2015, well in advance of the international deadline of 2030."
She said the Government was committed to working on other important international environmental issues, such as climate change, fossil-fuel subsidy reform and the conservation of the oceans.
Ms Adams will host an event at Parliament on Tuesday with scientists, industry leaders, non-government organisations and the diplomatic community to celebrate the anniversary.
