Kaiwharawhara railway station is a dual island platform railway station on the North Island Main Trunk (NIMT) and the Wairarapa Line in Wellington, New Zealand. It is the first station north of Wellington, and is served by trains operated by Tranz Metro as part of the Metlink network on the Melling Line, the Hutt Valley Line and the Kapiti Line. Three diesel-hauled carriage trains, the Wairarapa Connection, Capital Connection and Overlander services pass through the station but do not stop.
Kaiwharawhara has a unique platform arrangement for New Zealand. Looking north, the left-hand island platform is for up trains, the right-hand for down trains. The inner faces are used by Kapiti Line services on the NIMT, the outer faces by Melling Line and Hutt Valley Line services on the Wairarapa Line. Just north of the station the NIMT climbs an embankment towards the bridge that takes it across the up Wairarapa Line track and Hutt Road to Tawa No. 1 Tunnel.
