England's pace attack dominated day one of the third Test against New Zealand in Hamilton, leaving the hosts at 315 for nine at stumps. Despite a century opening stand, New Zealand's middle order crumbled, with Matthew Potts claiming three wickets and Gus Atkinson impressing with 3-55. Despite Williamson's presence, his dismissal to Potts - the fourth in five Tests - initiated a collapse. Daryl Mitchell (14), Phillips, and Blundell (21) followed with poor shot selections, leaving New Zealand struggling at 231 for seven.
