A 49-year-old man has been charged after sailing across the Tasman Sea from New Zealand to Australia with his six-year-old daughter in an alleged custody dispute.

The pair were located on the New South Wales south coast on Thursday.

Alan Langdon first disappeared with his daughter after leaving New Zealand's north island in his sail boat on December 17, sparking an international manhunt. The pair arrived in Ulladulla 27 days later.

Que was reunited with her mother, Ariane Wyler, on Sunday morning with the assistance of a child recovery agency.

Col Chapman from Child Recovery Australia told the ABC it was the second time he had been hired by Ms Wyler. He said Ariane and Que were reunited in New South Wales on Sunday.

Langdon was charged with "taking a child from New Zealand" but told the ABC a broken rudder forced him to cross the Tasman sea in a 6.4-metre catamaran with his daughter. He said his initial plans were to sail north to the Bay of Islands for Christmas. Almost one month later, he turned up 2,600km off course in Ulladulla.

"I tell you, I learned a lot about sailing," Langdon told the Milton Ulladulla Times on Wednesday.

"Yes, we are safe and well. We were always safe -- we just couldn't let anyone know."

Que's parents have reportedly been embroiled in an ugly custody battle before the father and daughter set sail from Kawhia Harbour.

He told the ABC on Sunday the unplanned reunion was "a bit hard to grasp".

"We came in to have some breakfast and while I was preparing breakfast, Que went to the toilet. And when I called out, I realised she wasn't there," he said.

"Be strong. I hope you are alright. I send you always my strength."

Langdon is expected to be extradited to New Zealand to appear in Tw Awamutu District Court on January 25.

"A 49-year-old man is due in Te Awamutu District Court on January 25, charged with taking a child from New Zealand," Detective Sergeant Bill Crowe said.
