Crematoria in Auckland are switching from gas to LPG to clear a backlog of funerals caused by the closure of the Maui gas pipeline.
Mangere Memorial Gardens manager Noelene Mudgway says all crematoria in Auckland were forced to close.
Ms Mudway says her service has been forced to postpone about five funerals every day.
She says specialists have been brought in to make the switch to LPG and the service should be able to start clearing the backlog by later in the day.
Meanwhile, various small businesses are being told they can start using gas again.
However due to conservation efforts by consumers, Vector says another band of customers can now be brought back on to using gas.
Small businesses, such as shops and cafes are being told they can start using gas again but only after they have been contacted by their gas retailer.
Big bakeries too
Goodman Fielder says its bakeries have been given priority access to gas and will be back in the next 24 hours.
It says consumers may notice a lack in quantity and variety of bread because bakeries have been focussing on making simpler products that are quicker to produce.
The company says it is too soon to know how much the leak has cost Goodman Fielder or to decide whether it will ask for compensation.
Goodman Fielder produces about half of the bread in New Zealand.
