Marmite lovers are facing a three-month extension to Marmageddon.
Manufacturing of the yeast-based breakfast spread was halted last November due to quake damage at the Sanitarium Christchurch factory.
It was expected to restart in July.
But Sanitarium last night confirmed its engineers had found additional structural damage in the factory.
General manager Pierre van Heerden said Marmite production was now not expected to restart until October.
