Latest - Repeat offenders identified as being 'high risk' of making dangerous tackles will not be sanctioned off the field while Super Rugby trials a new law this season.
World Rugby said last week that it would trial a suite of law amendments in several competitions this year in an effort to improve player safety.
The High Tackle Warning, which was trialled at the Under-20 World Championship last year, would be implemented in Super Rugby, which starts on Jan. 31.
Under the trial at the under-20 tournament, if a player received two warnings for high tackles they would be automatically banned for one match.
SANZAAR, however, said the trial would be used only for educational purposes this year, with repeat offenders given time to change their tackle technique.
SANZAAR will review every game to identify poor tackle technique and liaise with players and their coaches to try to change their behaviours.

What next for Conor McGregor?
Conor McGregor's spectacular 40-second demolition of Donald 'Cowboy' Cerrone in UFC 246's main event meant the question of who next for the Irishman came even earlier than expected.
Floyd Mayweather, Manny Pacquiao, Jorge Masvidal, Kamaru Usman and even Khabib Nurmagomedov were all quick to raise their hands as potential next opponents shortly after McGregor ended a period of more than three years without a win.
Yet McGregor was uncharacteristically vague when plotting the next step in his 2020 rehabilitation season.
With many of his suitors sitting ringside, fans and media expected the Dubliner to pick a fight, as he so often has done in the past.
Instead he was non-committal on who he would face next, offering only: "Any of them can get it."
Umaga called up to England
Rookie England first-five Jacob Umaga could soon find himself playing against his uncle's former team, the All Blacks.
England rugby coach Eddie Jones has picked eight uncapped players, including Umaga, the nephew of former All Black captain Tana Umaga, in his 34-man squad for the Six Nations.
Seven players from crisis-hit English and European champions Saracens are included but Jones says his only interest in the salary-cap scandal was how they performed for England.
England's most successful club have formed the backbone of Jones's England team since he arrived over four years ago but they are now in turmoil, with many players' futures uncertain, after they were handed an automatic end-of-season relegation from the Premiership for another breach of the salary cap rules.
Jones, a former coaching consultant with the London club, said that his job was simply to get the all the players to focus on England's opening game, away to France early next month.
