That number was halved by the evening and on Sunday 80 customers in 12 areas remained without power.
On Monday night up to 20 remained in the dark.
Today Mr Gough said all outages would be fixed by the end of day.
"There is nothing we have seen that tells us we are not going to get there," he said.
"It is hard going now - we are into the gnarly stuff," he said.
Remaining outages were in remote districts where two or three customers shared a line through forested areas.
"We are having to go through, clear branches, energise and then clear little bits of vegetation we didn't see because it's at the top of the insulator - so it is just a wee bit messy now.
"The country is a bit more challenging as well, so it is slower."
The lines company was also working to restore hot water to hundreds of customers. It has the ability to turn off the hot water cylinder in many homes through a power surge, which helped its network cope with peak demand.
Mr Gough said during the storm hundreds were hundreds of surges as trees fell onto lines.
It was an easy fix but a widespread problem.
"We are just going from power pole to power pole with faultmen and technicians - everyone is out there today."
Staff on the ground included crews from Taupo and Rotorua, the areas that were first expected to be hit by Cyclone Cook.
Mr Gough said if people remained without electricity, hot water or had any other issue "we need them to tell us".
He said the good weather was a blessing.
"If that bloody storm had hung around it would have taken us a hell of a lot longer, that's for sure."
