The Blues apart, once the New Zealand teams build momentum and put phases together, they invariably come away with points. After an uncertain start in Melbourne against the Rebels late last month in the first transtasman clash of the season, the Hurricanes finished well over the top of the home side for a 50-19 victory.
The same applied for the Highlanders in their 43-17 win over the Brumbies at Forsyth Barr Stadium. Next week the Chiefs play the Reds in Brisbane and another New Zealand victory is almost guaranteed.
The culling of the Western Force this season to cut the Australians from five to four teams may have upped the quality slightly across the Tasman, but that hasn't been apparent in the two transtasman matches.
The Waratahs are third on the table with five wins from seven (but have yet to play a New Zealand team), and the Rebels are sixth with four wins from seven (but have played only the Hurricanes).
The Reds, now back down in 12th place, had a harder edge at the start of the season thanks possibly to the coaching of notorious task master Brad Thorn, but will now almost certainly fade due to the collateral damage of injuries - a reality of the competition that New Zealand sides also cope with far better.
That's the other advantage on this side of the Tasman - greater depth and an ability for inexperienced players to enter a team and perform almost straight away due to the structures and coaching quality.
There is angst in Australia at the inability of their teams to break this extraordinary streak that began in 2016, and there could be pain ahead - three of the Crusaders' next four matches are against Australian teams (Brumbies, Rebels and Waratahs).
