Dave Rennie has confirmed New Zealand lodged a complaint with World Rugby over how the scrum was officiated at Ellis Park — though he's keeping the specifics close to his chest. The Boks dominated the set-piece in the first half, with De Groot, Taylor and Lomax repeatedly going backwards, and Rennie knows South Africa will come after the same target in Cape Town. Beyond the scrum, he's identified discipline and contact-area go-forward as areas needing improvement — the Boks' early-phase energy forced too many soft penalties and easy entry into the All Blacks' 22. Rennie is also openly wary of the 'Boklash' after the Boks' uncharacteristic error count in the 33-16 defeat, but his focus is on New Zealand lifting their own level rather than fixating on what the Boks will bring. Whether the World Rugby intervention shifts scrum officiating — and whether that changes the game's complexion — is the live question heading into the series decider.
