Closer perusal of the scorecard reveals the following:
Extras
Australia 27
NZ 5
Of those extras, 16 were byes - four deliveries from Tait which Haddin missed and ended up on the long stop boundary fence. Then another 10 were wides.
There's the match right there. Absolutely woeful bowling, and some ordinary wicketkeeping (though you can't blame Haddin too much as Tait, true to form, was all over the place with his line and length bowling at 155kmh).
