That means they will play at home against the lowest qualifier and will keep playing at home for as long as they keep winning.
At the moment, eighth is a battle among the Sharks, Bulls, Waratahs and Blues, but the Lions and Stormers could come into the reckoning if they can't hold on to their current conference-leading spots.
The picture changes remarkably for the rest of the New Zealand teams. With five rounds left, there is still ample room for surprises.
However, based on current form, standings and competition points, there's a reasonably solid framework from which to start seeing the future.
It's forecasting a crazy situation where, say, the Hurricanes could come within a whisker of topping the group yet find themselves seventh on the table and facing a brutal away knockout game - crazy because they will most likely finish with more competition points than three of the other teams who host a quarter-final.
At this stage, the team who finish fourth in New Zealand, and seventh overall, are on track to play the Stormers in Cape Town or Brumbies in Canberra.
The picture won't be any fairer for the teams who finish second and third in the New Zealand Conference. It is almost certain they will have more competition points than the team they play in the knockout round but it won't matter.
With a home quarter-final guaranteed to the four conference winners, the second-placed New Zealand team are on track to finish fifth overall and play the team who finish fourth overall.
Best guess at this stage is that the winner of the South African Conference containing the Lions, Sharks, Kings and Jaguares will finish fourth. From a New Zealand perspective, the opponent doesn't really matter so much. It's the fact they will have to take a long-haul flight to South Africa that will trouble them.
Neither the Sharks nor Lions have looked particularly fearsome, so a quarter-final in the Republic isn't the daunting prospect it once was, but the issue will be the knock-on effect of the travel.
It will be a big ask to win a quarter-final in Africa one week and return to New Zealand or Australia and win a semifinal six or seven days later.
For the New Zealand team who finish third, the scenario will be much the same. They will most likely finish sixth overall and be looking at a trip to South Africa or Australia.
The latter would be preferable in one regard but the Brumbies are arguably the strongest non-New Zealand side in the competition.
Predictions are never wise, but there are certain truths that can be stated in regard to the last five rounds ... namely that the intra-New Zealand Conference games will be the destiny shapers.
Those are the big-swing games where the winner knows they will get the jump on the team they beat.
Given the points situation, the Highlanders could all but bury the Hurricanes' hopes of topping the table if they continue their winning streak and repeat last year's final heroics by winning in Wellington on May 27.
If they do that, then beat the Kings and Jaguares on the road, then their fate will be in their own hands when they meet the Chiefs in Dunedin in the last round on July 16.
For the Chiefs to have as much resting on that last encounter, they must firstly win a tricky encounter against the Waratahs in Sydney and then defeat the Crusaders in Suva after the international break.
That game in Fiji will have huge consequences, too, for the Crusaders who, along with the Hurricanes, have three local derbies left. The Crusaders have lost two of the three they have played so far - the only losses they have suffered in 2016. Even if they win overseas against the Chiefs, they still have to play the Hurricanes on the last weekend.
As for the Hurricanes, they are in do-or-die territory each week now as they face the Highlanders, Blues and Waratahs in Sydney before they head to Christchurch. They have to keep winning to top the pool.
The Blues have to overtake one of their New Zealand rivals to grab a playoff spot, but really need to win tomorrow morning. Even if they don't, they will fancy they can pick up points against the Force and also in the last two rounds when they host the Brumbies and Waratahs. Their chances rely a lot on results elsewhere going their way.
