After being whistled out of the third test last Friday night, adjusting to unpredictable umpiring calls needs to be a major focus for the Silver Ferns tonight.
The plethora of penalties in the last match doesn't suffice as an excuse for the performance or the result - a dominant Diamonds side thoroughly deserved their victory in Adelaide - but the constant infringements from the Ferns negated the small patches of momentum that they had in that match.
Given their crucial role (in no other team sport do the officials have such a constant and critical influence on the action) umpiring is always a tricky aspect of these trans Tasman contests.
The neutral umpires from second tier nations struggle to cope with the sheer speed of the game, while the players can find it difficult to adjust to a different style of officiating than they have during the ANZ Championship season.
With a new set of umpires (from Jamaica, Trinidad and Tobago and South Africa) for the Australian leg of the series there were some unusual interpretations last Friday night, including numerous penalties against the Ferns for technicalities around the centre pass.
