Brexit Pacific impact

According to RNZI, Roderick Drummond said modes of delivery would have to change but he said the UK and the EU have a shared vision for supporting development in the Pacific.

That's according to Yurendra Basnett, the country economist and team leader of the Asian Development Bank's mission to Papua New Guinea.

Mr Basnett says one of the longer term effects of a British exit -- or 'Brexit' -- would be the need to renegotiate partnership agreement with Europe in the Pacific.

The provisional agreement between the European Union and PNG provides the country with duty free access to Europe and Britain.
