New Zealand moved into the World Cup quarter-finals by predictably beating Georgia in bonus-point fashion - but it was a performance laced with errors.

And they appeared to suffer an injury scare when skipper Richie McCaw made a 60th-minute exit after being on the receiving end of a crunching tackle and immediately had ice applied to two separate areas on his leg, summing up New Zealand's night.

The world champion All Blacks' 43-10 Millennium Stadium triumph tightened their grip on Pool C and secured a last-eight spot, yet coach Steve Hansen was not impressed.

"It wasn't one of our better ones. It will give us plenty to go home and think about," Hansen said.
