Despite losing the morning session to rain, Williamson orchestrated New Zealand’s dominance as they extended their lead from 340 to 657 before being dismissed for 453 in the final session under the floodlights at Seddon Park.
England, having already clinched the series with victories in Christchurch and Wellington, found themselves struggling at 18 for two at stumps, with Jacob Bethell unbeaten on nine and Joe Root yet to score, facing an imposing target of 640 runs for victory.
England’s task may be further complicated by the absence of captain Ben Stokes, who exited the match with a hamstring injury and remains uncertain to bat.
Tim Southee, playing in his farewell test on his home turf, received a rousing reception from the crowd but fell for two while attempting his 99th test six. The spectators erupted once more when Southee dismissed Ben Duckett for four with a clever delivery.
Zak Crawley also fell early for five, becoming Matt Henry’s sixth victim of the series with a leg-before-wicket decision.
Despite the anticipation for a declaration that never materialized, Daryl Mitchell (60), Mitchell Santner (49), Rachin Ravindra (44), and Tom Blundell (44 not out) all contributed with the bat. However, it was Williamson’s masterclass that stood out.
Williamson, who started the day on 50 with New Zealand at 136-3, navigated some tense moments before reaching his 33rd test century and seventh at Seddon Park. His partnership with Ravindra set the tone before he accelerated towards his milestone with a trademark six.
Another crucial stand with Mitchell pushed the lead beyond reach for England, surpassing the record fourth-innings chase of 418. Williamson eventually fell for 156, attempting a sweep shot off Shoaib Bashir.
Bethell was England’s standout performer with figures of three for 72, including the crucial wickets of Mitchell, Southee, and Henry in quick succession.
