Canterbury and future Crusaders coach Scott Robertson says attacking sides will have more phases with the ball under the new rules.
This would make the defending side's job more difficult.
"The first few weeks everyone will look at everyone else closely," he said.
Taranaki boss Colin Cooper says fans and players can expect a more exciting style of rugby but warns that attacking players will need to protect the ball more closely.
Reduced injuries in the ruck would be an added benefit.
"I think it'll be clearer for the fans, clearer for the refs and more tries scored," the ex-Hurricanes coach said.
Auckland coach Nick White, whose side were runners-up to Canterbury in the 2015 competition, says his side will need to adapt quickly.
"Because there's not a lot of contesting at the breakdown, there'll be a lot of running," White said. "At times you're going to have to do a lot of defence.
Hawke's Bay coach Craig Philpott, whose side earned promotion to the Premiership, agreed.
"You're certainly not going to be able to get the ball as easily as you used to, so teams are going to have to be innovative and react."
