Casey Williams was once again relegated to chief time-keeper and drinks deliverer, with the star defender failing to recover in time from a knock to the knee she suffered in the build-up to the opening test. With a tight turnaround between test two and Sunday's finale in Christchurch, New Zealand coach Waimarama Taumaunu opted to cautious approach with her skipper.
Even without the spectacular aerial abilities of their captain, the New Zealand defence was impressive, as Katrina Grant and Leana de Bruin combined to suffocate the Australian shooters.
They were strongly assisted by wing defence Anna Harrison, who long limbs again caused problems for the Australian attack, as they struggled to sight their shooters.
After a lacklustre showing in their 54-52 opening test loss in Melbourne, the Australians promised a more confrontational approach on defence tonight.
But despite their more committed efforts, they struggled to ruffle the New Zealand attack, as Camilla Lees and Laura Langman demonstrated strong patience.
Feeding off a wealth of turnover ball coming out of their defence end, van Dyk and Tutaia combined for a near-faultless shooting performance, missing just one goal in the first half to shoot the Ferns out to a 31-19 lead at the long break.
Not surprisingly, Lisa Alexander opted for wholesale changes at halftime, introducing Renae Hallinan (WD) and Madison Browne (WA) in to the midcourt, with Kim Green moving to centre in place of captain Natalie von Bertouch, who looked to be struggling with a calf injury.
Bassett was also introduced at goal shoot, in place of Cox, whose shooting numbers fell away late in the second spell.
The changes sparked a strong comeback from the Australians, as the speedier midcourt found easier passage through New Zealand's zone defence. Very soon, the Ferns 12-goal halftime lead had been cut to nine, then seven, then five, then three, as turnover by turnover Australia systematically pegged back the lead.
A late Katrina Grant intercept ensured the Ferns stretched their lead back out to five heading in to the final turn. But taking in to account the fighting qualities of the Diamonds, the game was very much still in the balance.
