This is a list of New Zealand television-related events from 2005.
This is a list of programs which made their premiere on a New Zealand television network that had previously premiered on another New Zealand television network.
Programs that have their free-to-air/subscription television premiere, after previously premiering on the opposite platform (free-to air to subscription/subscription to free-to air) are not included.
In some cases, programs may still air on the original television network.
This occurs predominantly with programs shared between subscription television networks.
