An injured Waisake Naholo follows All Blacks doctor Tony Page from the field during the clash with the Pumas.

All Black Waisake Naholo has apparently found a "miracle" treatment for a broken bone in his leg and may be available for selection in coach Steve Hansen's World Cup squad, reports say.

The Fiji Times is reporting that Naholo, who suffered a cracked fibula in New Zealand's Rugby Championship win over Argentina in Christchurch last month, travelled to the Fijian province of Nadroga to seek alternative treatment in the hope of a quick fix ahead of rugby's showpiece event in England.

The report goes on to say it was Naholo's uncle, Isei Naiova, who contacted the Highlander about the treatment which involved six days of traditional medicine in a rural place called Nadroumai Village.

"If you want to play in the Rugby World Cup, get on the plane and come here," Naiova reportedly told his nephew.

After almost a week of treatment, Naholo apparently lost his limp and was able to do light exercises and hopes of making the All Blacks' World Cup squad were reborn.

"Growing up here in the village, this was nothing new. I have seen it happen to people and even rugby players who came here and were healed," Naholo told the newspaper. "I believed in it as well and I think it will help in my recovery too.

"The movement of my leg is much stronger and after the first treatment, I am walking quite well compared to how I was when I got here.

"If I get the chance to be selected again for the World Cup I will be ready but for the time being I will just have to keep on working hard off the field as there are many top class wingers in the team that are there not just to make the numbers. They all mean business.

"I am still new and learning from them and it's a strange situation to be in because they are like my teachers and, at the same time, my competitors."

Naholo has had a standout year in Super Rugby and was one of the key components in Jamie Joseph's team landing their first title. He also impressed against the Pumas for the All Blacks before injury saw him sidelined. The World Cup starts on September 18.

New Zealand Rugby and the Highlanders are yet to comment on the report.
