New Zealand lead the best-of-four Constellation Cup against the Diamonds 2-1, with Sunday's clash in Perth to decide the winner.
The Silver Ferns beat Australia by a goal at the World Cup in July, and have twice beaten the Diamonds by the same margin during the current four-match series.
But Taurua just has to take one look at her country's poor Constellation Cup history to know her team has some way to go before it can be considered the best in the world.
New Zealand have won the series just once in nine attempts since its inception in 2010.
