There’s a convention centre right next door - with no parking facilities - that sees much larger events than the ones that happen at the Court Theatre, and that doesn’t seem to have any issues. Similar for the Isaac Theatre Royal. There are over 1000 parking spaces within walking distance. Get a grip mate.
This is unbelievable from the Court - this has been litigated over and over in the council’s previous decision about this site, this is just the Court trying to get their way again. Like you say, Te Pae doesn’t have a problem, and they see far more patrons than the Court will.
