Australian coach Chris Anderson has criticised the Australian Rugby League's judicial system as too harsh after Ben Kennedy was rubbed out of next month's Test against New Zealand.

Newcastle second-rower Kennedy was suspended for four matches on a grade one reckless high tackle after failing to have the charge downgraded at Thursday night's hearing.

However, his suspension was effectively extended to six matches after the judiciary decided the third Origin game on July 16 and the Test against the Kiwis nine days later would not count.

Kennedy received a penalty of 416 points for his 25th minute high shot on Queensland prop Steve Price in Wednesday's night second Origin match.

It included a base penalty of 300 points, 56 carry-over from a previous offence and another 60 loading for having committed that offence in the past two years.

The system in which NRL offences are applied to representative games only came into force this year.

"I just think this loading system is way too tough," said Anderson from Townsville, where Cronulla is preparing to take on North Queensland on Saturday.

"I appreciate they're trying to rub out repeat offenders but this is part of the game.

"He (Kennedy) is obviously not a dirty tackler, it's just every now and again that happens."

Knights chief executive Ken Conway said there were no grounds to appeal the decision and the club had accepted Kennedy would not play again until a round 21 NRL match against Manly in early August.
