The sisters and Lockley thought NZTA should pay for their tyres.
NZTA Northland highway manager Brett Gliddon said potholes are not unusual at this time of year when there's higher rainfall.
He said extra crews are working in bad weather and they repaired the pothole as soon as they were alerted.
"Crews will be back to check the situation and will monitor it until a permanent repair [can be] made during spring, when weather conditions are better suited to pavement repairs."
He said NZTA patrols the network daily and encourages people to report potholes or damage immediately.
"The NZ Transport Agency will consider the individual circumstances for each case before making a decision about compensation."
