Tax officials formally scheduled a review of New Zealand's foreign trusts regime a month before the Prime Minister's lawyer and his associates began lobbying the Government, the Labour Party says.
Labour leader Andrew Little said the inclusion of the review on the Inland Revenue Department's action plan in November 2014 showed how serious it was about cracking down on the secretive trusts.
A month later, Mr Key's personal lawyer Ken Whitney, who specialised in foreign trusts, met then-Revenue Minister Todd McClay.
Mr McClay, who was new to the portfolio, put an end to the review five months later, saying the IRD did not have the capacity to take it on.
In Parliament yesterday, Mr Little claimed the real reason the review was dropped was the Government's closeness to the foreign trusts industry.
