New Zealand have won the past 34 Tests against Wales in a winning sequence that stretches back to 1953, with the All Blacks scoring more than 50 points on each of their three previous visits to Cardiff over the past five years.
New Zealand and South Africa are currently unbeaten in the southern hemisphere table, competing for top spot before the Nations Championship play-off weekend at the end of the month.
Rennie, however, says his side are not concentrating on trying to close the points-difference gap on the Springboks.
“It’s just a Test match and our focus is this week,” he insisted.
“We’ll probably be looking at things going into the last game, where it might be a little bit clearer around what we need to do.
“I think South Africa are about 70 points clear, so if we end up on the same amount of points, it’s unlikely we’d catch them.
“There’s a real danger to go out and think you need to score X amount of points, you end up overplaying and getting embarrassed.
“We’ve got a clear plan around how we want to play and whatever happens, happens.”
