All Blacks coach Steve Hansen has thrown his support behind the new interpretations of the tackle law set to be introduced later this year.
World Rugby will test the two rules at the upcoming World Rugby U20 Championship and U20 Trophy, in a bid to combat the risk of head injuries.
The laws lower the acceptable height of a tackle to 'below the nipple line', and additional punishments for transgressors will be implemented.
A high tackle warning will be issued if the tackler does not bend at the waist when tackling and there is clear and obvious head contact for either player.
Hansen said they'd provide a much clearer benchmark for both referees and players.
"I think it's good…it's better than below the shoulders, because there's quite a lot of games where you make the tackle and it doesn’t look to be a bad tackle, and yet it's been penalised," Hansen told media on Sunday.
"The clearer and more simple you can make it, the better. We all know where are our nipples are. Hit below that and you're going to be okay."
It's not a blanket solution to solving the issue of concussion, but should mitigate some of its inherent dangers, Hansen continued.
"We're still going to get concussions. When you have three people piling into a collision, not everyone's putting their head in the right place.
There has been a spate of head-related injuries in the All Blacks ranks over the past few seasons, most notably with hooker Dane Coles, and more recently, Ben Smith and Ryan Crotty.
"There's still going to be unavoidable ones because it’s a really physical game, but what we can make sure is that we really look after those people when it does happen to them.
"I think that's what we're seeing from all the franchises and ourselves, is that's happening."
If the trial is deemed successful, World Rugby has indicated they may look at introducing the trial law at other competitions.
New Zealand head into the tournament as defending champions and will face Australia, Wales and Japan in pool play.
