Skipper Greg Gemmell said they were notified about the stricken yacht about 3.30pm on Wednesday.
They required an exemption from Maritime New Zealand because the rescue was more than 12 nautical miles (22.2km) at sea.
Multiple agencies worked together for about two hours to plan the rescue.
Coastguard Houhora set off about 6pm, with four crew and two shore-based crew aiding them.
Conditions were fine until they arrived near the vessel on the west coast, about two hours after leaving shore.

It was dark, there were swells, and 15-20 knots of wind to grapple with, making for an unpleasant ride.
Gemmell said the yacht’s crew was relieved to see Coastguard arrive.
They decided the safest option was to place two of the four Coastguard members aboard the yacht.
Gemmell explained those on board were fatigued, and by that point, only the captain was capable of operating anything.
Fatigue was often a trigger for other things to go awry, he explained.
“I think when you’re in that situation, reassurance is as good … a tool as anything … when you know you’ve got some fresh energy there to help.”
Once the two Coastguard members were on board, the vessel shadowed the boat back to calmer waters.
“I think it just gave the whole spirit on board a positive turn that they probably were going to be okay,” Gemmell said.

About 2am, the yacht’s captain, who had rested, took over steering.
“The strength and the energy required to operate it [the steering] was very gruelling on them,” Gemmell said.
He explained about 80% of the trip was shadowing the yacht, with 20% spent towing. Had they decided to tow the whole way, it would have taken far longer.
Gemmell said the yacht’s crew knew they were going to struggle making it back without help.
No other boats were in the area, he said.
“They were certainly well equipped with safety gear and all that, so I think they knew what they were doing, but these things can happen to anyone, you know.”

He feared had they stopped and gone to bed without seeking aid, the yacht would have washed up on the coast.
The Ayacht’s crew was tired but uninjured when they arrived back to Northland shores about 5am.
Gemmell said Coastguard Houhora was operated by volunteers, and they all had day jobs.
“We’re in a remote area here, it’s a small little community we have and having even six people to take that time out of their life is a big effort.”
