Ports around the country - which are excluded from Official Information Act requests - could see that challenged soon.
Labour MP Darien Fenton's private member's Bill, seeking to increase transparency for publicly owned ports, was drawn in the ballot last Thursday.
Most of the ports around the country are council or regional council-owned.
The Bill would put ports under coverage of the Official Information Act and would also create "good employer" obligations.
Council of Trade Unions president Helen Kelly said ports coming under the same transparency as almost every other public entity would give people access on how decisions came to be made.
She said it was "great news", coming on the week the Maritime Union of New Zealand had written to the Auckland Council seeking the Ports of Auckland be accountable for the money spent on its "ill-conceived contracting plan".
"The Ports [of Auckland] were able to develop and progress their 'strategy' of seeking to sack all the wharfies and contract out their work.
"It was a failed plan that cost it millions of ratepayers' dollars and without any right for the public to request information from the Ports regarding how they developed that strategy," Ms Kelly said.
