Revenue Minister Michael Woodhouse is getting advice on Australian and British tax laws that target multi-national companies.
However, he told Parliament this afternoon that he is satisfied New Zealand already has rules in place dealing with the same issues.
A major Herald investigation this month has found the 20 multinational companies most aggressive in shifting profits out of New Zealand overall paid virtually no income tax, despite recording nearly $10 billion in annual sales to Kiwi consumers.
The investigation was raised during today's question time by Green Party co-leader James Shaw.
Woodhouse, during the exchange with Shaw, didn't accept there were "deficiencies" in New Zealand's tax rules that hadn't been addressed.
