Further extension of the electrification north from Waikanae to Ōtaki remains a possibility. A group known as "Save Kapiti" is actively campaigning for the extension. The Otaki Community Board also supports the extension of electrification. Provision has been made during road earthworks north of Waikanae for a future crossing loop between Peka Peka and Ōtaki. In 2012 the Greater Wellington Regional Council investigated extension of the electrification with Matangi trains north of Waikanae to Ōtaki (estimated cost $30 million for the Ōtaki project) and north of Upper Hutt to a new station at Timberlea.
