Almost all services have resumed as the ash from the Puyehue Cordon-Caulle volcano in Chile moves south over the Tasman.
But with the volcano still erupting, the Volcanic Ash Advisory Committee is unable to say whether an ash cloud could return in time to disrupt school-holiday flights from Friday.
Forecaster Steph Bond said it was impossible to predict if and when the cloud would return.
"We can't really say what will happen beyond the next 36 hours," Ms Bond said.
"At the moment, we have it all south of the Australian continent and we don't expect the ash to affect us for the next 24 to 36 hours."
Ms Bond said the ash cloud had broken up significantly and looked like it would dissipate over the southern oceans.
But while seismic activity in Chile has declined, officials have said there is the possibility of another explosion.
Most major carriers cancelled flights to New Zealand for the entire weekend, as the ash cloud lingered.
Qantas and budget airlines Jetstar and Virgin said services to and within New Zealand were suspended until at least today.
As well as blanket cancellations between Australia and New Zealand, Qantas said its Buenos Aires services had been delayed by 24 hours and Johannesburg flights were operating out of Perth.
Since the volcano began erupting on June 4, airlines have shed tens of millions of dollars, with Qantas estimating it lost $21 million from last week's delays alone.
