With the league seeking a "culture of compliance," NBA commissioner Adam Silver said on Friday the new rule changes could involve, "suspending executives ... taking away draft picks ... voiding contracts.

"All those provisions are on the table. The ultimate goal is compliance."

Speaking after two days of meetings in New York, Silver added: "Our teams want to know that they're competing on a level playing field and frankly don't want to feel disadvantaged if they are adhering to our existing rules."

If a player/agent solicits unauthorised benefits or contact regarding contract matters, a team must be notified within 24 hours, under the changes.

Also, five teams each year will be randomly audited to make sure no rules have been broken.

Fines for tampering with team or player personnel would increase from $US5 million ($A7.4 million) to $US10 million, and increase to $US6 million for a team and $US250,000 for a player for unauthorised agreements.

Other changes approved by the board included adapting language in the league regarding travelling violations and establishing a deadline for teams to submit line-ups 30 minutes before game time, 20 minutes more than previously stated.
