Super Rugby format needs to be looked at - Rennie

The Chiefs were hammered 45-25 by the New South Wales Waratahs on Friday to put Rennie's table-topping side under pressure to try to win the New Zealand conference and secure home advantage throughout the playoffs.

"There's going to be four quarter-finals and two of them are going to be in Africa," Rennie told reporters in Sydney.

"Considering they've got six teams and half those games are going to be there... I guess they put a lot of money into it, so that's the way it is.

"In the end, we've known about the comp. It is what it is. It means if you don't win your conference, you're travelling."

The governing body introduced three country-specific conferences to the competition in 2011 when it expanded to 15 sides, five in each of Australia, New Zealand and South Africa.

That allowed for at least one side from each country to make the six-team playoffs at the end of the season.

The competition, however, expanded this year to 18 teams to incorporate a sixth South African side, the Kings, and introduced two new teams in Argentina and Japan, both of whom joined an eight-team African group split into two conferences.

Based on total points, New Zealand sides occupy the top-four spots after games on Friday but according to the competition rules, the Chiefs (42) would be ranked first, the Canterbury Crusaders (41) would be fifth, Wellington Hurricanes (40) sixth and Otago Highlanders (38) seventh.

The Waratahs, as the leaders of the Australian conference would be ranked third on 34 points, while the Lions (37) would qualify second with the Bulls (32) fourth as the respective leaders of the two African groups.

South Africa's Sharks, who are in the same conference as the Lions, would take the eighth and final spot on 35 points.

The top four sides earn home advantage for the playoffs.

The draw also ensures that teams do not play each other, with the Bulls and Stormers (32 points) not meeting any New Zealand sides, which Rennie felt was unfair as he preferred a straight round-robin format between 16 teams.

"That's a fairer system, isn't it?" he said. "There's been a bit of talk about the fact that maybe the Stormers, Bulls they play 15 round-robin games and they don't have to play a Kiwi side.

"That's not a bad draw is it?"
