Auckland needs a dedicated Oval = cricket ground. 100%.
Just like the Tron, Mt Maunganui, Basin, Hagley & University Oval.
But the Aussie comparisons are a bit pointless. Apples v oranges.
Comparable sized cities Perth, Adelaide & Brissy all have the massive financial advantage of multipurpose ovals with 12 month use, cricket & AFL. The rich BBL with big crowds. The AFL with tonnes of cash. The Adelaide Oval was 'modernised' from a picturesque cricket ground into a concrete beast for the AFL. Bye bye grassy banks
Then Perth & Adelaide get enough ALM & Super Rugby (Perth) tenants to make their small rectangular grounds viable. Whilst Suncorp in Brissy has 3-4, year round tenants in the Broncos, Redcliffe Dolphins, QLD Reds & Roar.
Oh and don't forget whenever big football (soccer) or rugby (both codes) games come to Adelaide or Perth, they take them to their big Oval stadiums. There you are even further from the action than Eden Park. Ditto the huge MCG.
