It is understood the five New Zealand Super rugby coaches were given the option of missing their best players for a week or two half-weeks and they chose the latter.
They also have the small comfort of knowing that next year - when the All Blacks host England in June - is the last time it's likely to happen. There will be no June tests during the World Cup year of 2015 and after that the hope is that a restructured season - probably brought about by player power - means each competition will play in its own window.
The Crusaders are the worst affected, with nine of their players involved in the current camp. The Blues, preparing for an important match against the Brumbies at Eden Park, have eight players away. The Chiefs have six up the road in Mt Maunganui, although their players' involvement next week is mitigated by their second bye.
The Hurricanes have a bye this week, with the Highlanders' players not involved as they are in Perth preparing to play the Force.
For both Blackadder and Rennie, it's business as usual, although for the former, having just got his All Blacks to click over the last two matches - important wins over the Brumbies and Blues - he has lost them to the national team.
"We actually haven't altered anything, apart from our All Blacks not being here," he said. "It was always in the programme so nothing changes for us."
Rennie gets his players back a little earlier than Blackadder - tonight as opposed to tomorrow morning - but again, the Crusaders coach was philosophical about that.
The Chiefs coach, in charge of a squad already disrupted by injury, said: "We did it last year, it's not really a major issue.
"They won't get flogged there. It's more about getting their head around things, they'll do a lot of recovery stuff. Our guys will come back on Tuesday night. We'll catch up with them and get them up to speed with what we've done from a review and preview perspective so they're ready to go Wednesday morning."
