panic buying petrol has caused some petrol stations doing discounts price promotions to sell all of their product.

the RNZ website reports that successful sale as "gas stations being wiped out".

wiped out has one meaning I am aware of which is eliminated. the headline is an insane straight up lie for no reason whatsoever.

something wrong with this editor, man. but one fewer news website to bother reading from time to time due to its straight up lying is, for me, an improvement.
