The All Blacks have urged referee Craig Joubert to be extra-vigilant and punitive about the breakdowns in their semifinal shootout against the Wallabies.
After the Springboks, their staff and supporters heaped criticism on Bryce Lawrence for his rulings during the Wallabies quarter-final win, All Blacks assistant coach Steve Hansen joined those who were disappointed in the referee's performance.
He felt Lawrence had been too lenient, especially in the breakdown area.
"You are not allowed to go off your feet at the breakdown or hang on to the ball after the ref says 'ruck' so if they do that it will be great," Hansen said. "Then we can all have a good game."
South African Joubert and Alain Rolland from Ireland, who is controlling the opening semifinal between Wales and France, are favoured to also be duelling for the World Cup final role. Both exhibit a calmness in their duties. Nigel Owens from Wales has continued to be a semifinal assistant.
