The Black Ferns won last week's match 47-10 in Perth, and were hot favourites to take game two in the Laurie O'Reilly Memorial Trophy at Eden Park.
But although they only led 17-8 at halftime and were pushed hard by the Wallaroos for 60 minutes, the Kiwis kept their Australian counterparts scoreless in the second spell to shut out the win.
The New Zealanders hit first after just three minutes through Ruahei Demant, but Australia responded quickly, Mahalia Murphy busting through some weak Black Ferns tackling to dot down five minutes later.
A Kendra Cocksedge penalty extended New Zealand's lead after 23 minutes, then lock Eloise Blackwell crossed as the half-hour mark approached after a strong scrum and good work from centre Carla Hohepa.
Lori Cramer narrowed the gap for the Wallaroos right on halftime with a well-taken penalty, the Black Ferns taking a nine-point lead into the break.
Cocksedge nailed a 51st-minute penalty, before the Ferns upped the pressure with a couple of quick penalty taps and Hohepa powered over on the hour mark.
Forwards Charmaine McMenamin and Charmaine Smith rounded out the scoring with tries in the 66th and 80th minutes.
