New Labour Leader David Cunliffe has come under pressure to reveal whether a Labour-led Government would tear up National's pokies-for-convention centre deal with SkyCity.
Legislation enabling the casino giant to build a $400 million convention centre in downtown Auckland in return for hundreds of additional gambling machines and other regulatory concessions was reported back to Parliament this week.
Labour's view on the bill, included in the commerce committee's report, noted advice from officials that the bill - including provisions for SkyCity to be compensated if any regulatory concessions were removed - could be amended in future.
The report also says that Labour MPs "reserve the right to change the law when in government".
Green Party Co-leader Metiria Turei said Labour's position was similar to the Greens'.
