Volcanic ash spewing out of Mount Ruang is still causing disruption for Bali-bound holidaymakers.

Air New Zealand cancelled two flights at the weekend due to the ash making conditions "challenging", the airline said.

The cancellations come more than a month after clouds of gritty ash -- potentially hazardous to airline jet engines -- caused havoc for travellers in and out of Bali in July.

Thousands of travellers were left stranded as airlines worldwide had to cancel flights.

Air New Zealand's cancelled flights from Auckland to Denpasar on Saturday were NZ245 which was scheduled to depart at 4.30pm and NZ246, scheduled to depart at 11.25pm.

A make-up service is scheduled to leave Auckland on Tuesday at 10am.

The airline did not say how many customers had been disrupted with the cancellations.

Jetstar cancelled five flights between Australia and from Bali today, stating the "safety of passengers and crew is our first priority".

Virgin also announced cancellations on Sunday -- saying its team of meteorologists advised conditions were still unsuitable for flying in and out of Denpasar.

It cancelled six flights from Australia to Bali on Monday, following the 14 cancelled flights on Sunday.

"We have been advised that Mt Ruang continues to erupt and winds are blowing in an unfavourable direction," the airline said.
