The 2023 Port Waikato by-election was held on 25 November 2023. The by-election was triggered by the death of Neil Christensen, who was a candidate for the ACT Party. Christensen's death occurred after the close of candidate nominations for the 2023 New Zealand general election, but before polling day. The by-election was won by National incumbent Andrew Bayly, who has held the Port Waikato seat and its predecessor Hunua since 2014.
