The head of the charity Oxfam says New Zealand could be doing more to help alleviate poverty on a global level.
Speaking on TVNZ's Q+A programme, Oxfam International Executive Director Winnie Byanyima told Corin Dann that rich countries like New Zealand needed to work on a global tax reform to ensure big firms paid their fair share of taxes.
"Here in New Zealand, I know about 20 companies that are very aggressive in tax-dodging, are paying almost no income tax," she said.
She said the charity was not anti-globalisation but under the current model, wealth was not being fairly distributed.
"We can't have a globalisation that's based on rewarding just the owners of capital. That's a wrong and unjust globalisation."
She called on New Zealand to lead the way in implementing a living wage to workers.
"These are some of the things that can be done in a global economy."
