New Zealand's best rugby players are returning to work today, as all five Super Rugby Aoeteroa franchises hit the training park for the first time in two months.
With the move to COVID-19 Alert Level 2 and restrictions lifted around professional sport, the national game is edging closer to resumption.
Players and coaches will undergo strict medical protocols to ensure everyone stays healthy in a month-long 'pre-season' build-up to the now-domestic format. Among those precautions, media are excluded from training sessions during this initial week of training.
The revamped competition is scheduled to kick off on June 13, when the Highlanders host The five NZ franchises will play each other home and away over 10 weeks, with two matches every weekend at 5:05pm on Saturdays and 3:05pm Sundays.
Each side will have two byes.
Matches will be played in closed stadiums, until the Government advises an approach for managing mass gatherings in controlled venues that will allow fans to return.
The venues confirmed to date are Hamilton's FMG Stadium, Wellington's Sky Stadium and Dunedin's Forsyth Barr Stadium, with Christchurch and Auckland yet to be announced.
Players must adhere to strict sanitation and hygiene guidelines, as NZ Rugby desperately tries to avoid anyone contracting the coronavirus.
But acting medical advisor Dr Deb Robinson believes the strict protocols put in place will prevent a mass competition-wide outbreak, if a player or coach tests positive.
"We've asked the players to keep their personal bubbles smaller than what they may have done at Level 2, as that decreases the risk of transmission," Robinson says.
"We are holding the players at a higher standard than the rest of the country, because we really want the competition to go well.
"If we get a singular case, it will very much be situational dependent. It will depend on who it is, how they present and how many people they have come in contact with.
"We don't think it will stymy the whole competition - the rules around contact tracing are exactly the same.
"It may create a hiccup or two, but I don't think it would result in the competition stopping."
