An investigation is underway after a number of cars were set alight in Auckland overnight.

And three of the cars belong to one family who are gutted that they now have no transport and bills to pay on property that has been incinerated.

Emergency services were called to Victor Street in Avondale just before 3am.

A woman posted on Facebook that the three cars belonged to her and her family.

"I worked so hard to pay for this car. I got it when I was 19," said one of the owners on Facebook.

"I have paid way over 10k and still have 4K left with no insurance.

"I can't even describe the feeling. Who the f**k could do this?

"My poor family has suffered and some cowards have think they have accomplished something great."

She was pleased her family were safe but said the situation was "f**ked".

A Givealittle page has been set up to help the family who have been left with "no transport".

More than $3000 has already been donated today.

The Herald has reached out to the owners.

A fourth car was burnt out near Mount Smart Stadium. It is unclear if that incident was linked.

Police confirmed this morning they were making inquiries about the incident.
