New Zealand Cricket seems unlikely to implement new laws allowing umpires to send players off.
The Marylebone Cricket Club, which is the custodian of the laws of the game, has changed the rules allowing umpires to penalise teams for poor behaviour.
That ranges from awarding penalty runs right through to be able to send a player off.
However each country will decide whether the laws are introduce domestically while the ICC will decide whether the new rules will apply at international level.
New Zealand Cricket's match officials manager Sheldon Eden-Whaitiri said there will be discussion with players, umpires and administrators about the proposed changes but doubts there will be any change as the current system works well.
"We've already got a pretty effective code of conduct in place and it is an effective tool for regulating player behaviour."
Eden-Whaitiri said it was not unusual for national boards to have different rules for their own dometic competitions.
John Stephenson, MCC Head of Cricket, said "we felt the time had come to introduce sanctions for poor player behaviour and research told us that a growing number of umpires at grass roots level were leaving the game because of it.
The MCC has also announced the dimensions of a bat will be reduced.
The bat change comes with the bat having dominated the ball in recent years whereby batters have been wielding heavier bats with greater depth, allowing them to hit the ball further.
The new maximum permitted dimensions of a cricket bat will be 108mm in width, 67mm in depth with 40mm edges.
A bat gauge will be used to ensure the new limits are enforced in professional matches.
Changes to bat sizes were recommended last July by the MCC's world cricket committee, which includes former Australian captain Ricky Ponting and Sri Lankan wicketkeeper Kumar Sangakkara.
The rules around the 'Mankad' have also been changed.
It will state that if the non-striker is out of his or her ground from the moment the bowler would normally have been expected to release the ball, the bowler is permitted to attempt to run him/her out.
This will keep non-strikers in their ground for slightly longer than the current Law and mirrors ICC's Playing Regulations.
The new Code of Laws will also be written in language that is neutral to both sexes for the first time.
As it stands, the Laws currently make all references to the male gender, with a disclaimer stating all such references apply equally to women and girls.
