IRD commissioner Naomi Ferguson told the committee her department would be ready to implement BEPS recommendations as they were made.
International tax avoidance came under scrutiny earlier this year with the leak of documents known as the Panama Papers outlining a web of transactions designed to minimise tax for clients of Panamanian law firm, Mossack Fonseca, and putting New Zealand's regime for foreign trusts under the microscope.
That regime is currently under review by former PwC chairman John Shewan, and Woodhouse told the committee that is on track to be completed by the June 30 deadline set by the terms of reference.
Woodhouse downplayed early steps to review the disclosure regime by the Inland Revenue Department, saying his predecessor, Todd McClay, asked officials what they would drop to put issues concerning transparency on the work programme, something they weren't prepared to do.
When pressed by Labour finance spokesman Grant Robertson, Woodhouse said he and his predecessor would have been concerned if there were plans to drop the foreign trust regime put before the minister by officials.
"What I understand is that that was subsequently clarified between the minister and IRD," he said.
