New Zealand stormed to their 50th Rugby World Cup victory, thrashing Namibia with 11 tries, but Ethan de Groot was sent out late for a reckless contact.

De Groot was handed a yellow card in the final 10 minutes for a high tackle on Adriaan Booysen, but a ‘bunker’ review upgraded it to a red.

Within 25 minutes, the All Blacks had scored a bonus-point fourth try.

Daminzie and Cam Roigard both scored twice to put them up 38-3 at the half.

English referee Luke Pearce had initially issued a yellow card to De Groot when his shoulder touched the head of substitute Booysen in a sloppy tackle.

However, with no mitigation, his call was quickly improved.

“We’ll look into it; there was a lot of shoulder to shoulder in that contact,” New Zealand head coach Ian Foster said on BBC Radio 5 Live.

“We’ll see what happens if we compare it to something that happened yesterday.”

On Thursday, France’s Romain Taofifenua avoided a red card for a high tackle, prompting further concerns about officials’ uneven rulings at the Rugby World Cup.
