The Australian camp has raised suspicions around the work of the Black Caps bowlers ahead of the Boxing Day test at the Melbourne Cricket Ground.
Batting coach Graeme Hick did not have a problem with New Zealand using bouncers against his batsmen, but did question why umpires did not step in and interfere during the Black Caps' legside attack in the opening test in Perth.
During the second innings, Black Caps pace bowler Neil Wagner delivered a legside barrage to Matthew Wade, with wicketkeeper BJ Watling setting up on the legside in anticipation of the tactic.

According to the ICC men's test playing conditions, umpires can call wides if they consider someone "to be bowling down the leg side as a negative tactic".
