In November 2011, Sanitarium shut down the sole production line of New Zealand Marmite at its Christchurch factory after a cooling tower at the factory was deemed unsafe, having cracked in the 22 February 2011 Christchurch earthquake and its aftershocks. On 19 March 2012, the company announced that its own stocks of Marmite had run out and the production line was not expected to be running again until July. 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".
