How good that roof would have been early last week when the first two days of the classic were disrupted by rain.
The stadium has been vastly improved on its northern and eastern sides where it has been incorporated in a private gym and recreation club but the old stand at the southern end and the sweltering concrete terraces on the western side still wait for upgrading.
The association has raised $10.5 m of the $18.5m it needs and hopes the balance will come from a mix of public, commercial and philanthropic sponsors.
As it stands, the stadium is not up to the standard the professional tour associations expect. Until the money can be found, Auckland's tournaments do not have an assured future.
Their director Karl Budge does a superb job signing up drawcard players for the tournaments but it must be wondered whether undisclosed appearance fees are Auckland Tennis' best investment. As Budge said himself this week, nobody who books a seat in advance is ever guaranteed to see a particular player.
So maybe it is time to put more of that appearance money into concrete and steel and a retractable roof. Now wouldn't that be something. They could name it after Serena.
