The Blues face the fewest - two (against the Highlanders and Chiefs), but face the added challenge of a trip to South Africa and the prospect of tough matches against the Sharks in Durban and Cheetahs in Bloemfontein.
Things can change quickly in the run-in when you're beaten by a New Zealand rival.
The Hurricanes quickly slipped to ninth on the table after their loss to the Chiefs in Wellington and the Blues were overtaken by the Crusaders after their defeat in Christchurch.
The Highlanders, last and out of the running weeks ago, can still play a big part in the competition if they beat one or more of the Kiwi teams in the final stages.
Another significant factor is the three-week break for next month's tests against France.
Being away from their franchises won't be such a big deal for the All Blacks, but injuries could have a big say.
