Green Party co-leader James Shaw added his voice to calls for a crackdown and said the issue had been brewing for some time and should have been addressed earlier.
"The Government will say they are working multilaterally with the OECD to address this tax rort, which is good, but the OECD has been trying to address this issue since 1979," he said.

"The [Herald findings] are consistent with the information that was starting to come to light towards the tail end of my own time as Minister of Revenue almost three years ago," he said.
