Yep national crisis alright. The factory is in Christchirch which got hit repetitively by massive earthquakes in 2011. I live a little north of wellington and
we felt the earthquakes. Anyway lots of people dislodged from homes, terror all round, and no marmite factory.
"Some supermarkets reported at the time they had already run out of stock, and there was only a few weeks of stock left in their distribution centres, leading to the dubbing of Marmite as "black gold" and the crisis as "Marmageddon"" according to Wikipidia
Apparently people also sold jars of
this size for lots of cash. (……Or it might have been the bigger size, about two of the ones pictured.)
And I can't eat it due to a gluten intolerance that doesn't react well with wheat. Actually that's an understatement, I get rather sick from wheat based stuff.
