Herald experts - Rugby World Cup semifinals

NZME's rugby experts make their predictions for the Rugby World Cup 2015 semifinals.

All Blacks v South Africa - Twickenham, Sunday 4am

Patrick McKendry

The All Blacks should have too many weapons and too much self-belief for a South African team which started this World Cup poorly, improved a bit, and somehow crept into the semifinals with a late win over Wales.

Wynne Gray

A better all round game although forecast wet weather puts more heat on the pack to quell the Boks. Worried about ref though.

Nigel Yalden

A more skilled bench and mental toughness means they will handle the tight moments of the game better that will come at the end of a very physical encounter.

Elliott Smith

Another classic between these two sides. But the All Blacks have had the wood on South Africa the last four years and their attack will prove too much for the Boks defence.

Dylan Cleaver

If they can shift the emphasis away from the setpiece, the All Blacks should be able to run the Boks off their feet.

Australia v Argentina - Twickenham, Monday 5am

Patrick McKendry

This is the Pumas' big chance. If they can start and finish the way they did against Ireland they should beat the Wallabies, who have looked good in parts but appear vulnerable to pressure.

Wynne Gray

Got their fright last week and Pumas will have doubts when they hit tough segments in this game. Foley v Sanchez goal kicking crucial.

Nigel Yalden

Last week's wake up call will be just the tonic for Chieka's mob to sneak another tight contest late in the piece.

Elliott Smith

The Pumas will gain enormous confidence from their close out against Ireland, while four big tests in four weeks is too much for the Wallabies who run out of puff.

Dylan Cleaver

Argentina will not be able to play the phase-to-phase style that worked so well against Ireland; the Wallabies have their number.
