Hi there – tough, I am sorry. There was some update around the alert levels today – check those out here – https://covid19.govt.nz/businesses-and-employees/businesses-and-services/
At this point, beyond the wage subsidy, and the small business loan, there are not too many other support schemes or financial assistance – there are new provisions around tenancies, but that is more protection if you can’t pay or the landlord wants to raise the rent – they can’t kick you out straight away for non-payment.
But to you point, I am not aware of current financial assistance for rent, or other overheads.
Sometimes you have to make the tough calls when you look at all of the facts – and if you can’t see it makes sense to stay open, then that may be a serious option for you to pursue.
