The Waikato Connection was a short-lived express passenger train between Hamilton and Auckland in New Zealand's North Island. It consisted of a weekday single return service using diesel multiple unit railcars. Like its southern counterpart, the Capital Connection between Palmerston North and Wellington, the service was operated by Tranz Scenic and run as a commercial venture. The service was restored in 2021 for a five-year trial as "Te Huia".
