The long-running New Zealand primetime drama has aired five episodes a week from Monday to Friday since 1992. But it will be cut back to three nights a week in 2025.
TVNZ chief executive Jodi O'Donnell said the decision was influenced by the state-owned broadcaster's new digital-first strategy.
Shortland Street's 34th season was due to begin in February, but a spokesperson was unable to confirm which days the episodes would air.
