This has prompted the Greens to threaten legislation to halt the project if and when they are in Government. That could be the case at the end of next year, just a few months after construction of the convention centre is expected to get under way. The Greens might stretch to repaying construction costs up to that point. But that would be a the limit.
The party views the heads of agreement as an attempt to bind future governments to stop them initiating further measures to tackle problem gambling. The Greens are seeking constitutional advice on governments breaking contracts with outside private interests. In New Zealand, however, Parliaments are elected for three-year terms and cannot be bound by the actions of their predecessors.
Fortunately for SkyCity, Labour is much more cautious with Shearer saying his party would have to see the fine print of the heads of agreement. Well, the fine print is already in the public domain.
There might be good reason for Shearer's caution, however. By the time that party and the Greens are sitting on the Government benches in Parliament, up to 1000 workers will be swarming over the construction site of the convention centre. Slinging them out of their jobs will not be an easy thing for a centre-left Government to do.
SkyCity can breathe easier.
