Referee Nigel Owens reveals some of his trademark wit calling out Scotland's Stuart Hogg for diving in a RWC match.

The Welsh man in charge of the game giving New Zealand a shot at Rugby World Cup glory, has a soft spot for Hamilton and recommends the Tron's nightlife.

Millions of New Zealand and Australian rugby fans are expected to turn on their televisions to watch Nigel Owens referee the World Cup final between the All Blacks and the Wallabies at Twickernham on Sunday morning.

But fans will also know that in his autobiography, Halftime, Owens speaks about his experiences in Hamilton and Auckland, among other international venues where he has refereed Tri-Nations matches.

He wrote he thoroughly enjoyed his few days in Hamilton and would certainly return.

"It was the place to be that weekend, and if you like plenty of nightlife then you will be very happy here," he wrote.

Although he admitted at first Hamilton was "not somewhere you would normally choose to go to in New Zealand," he said the smaller-scale Waikato Stadium rugby venue packed with 32,000 fans was "as good as they get".

However, he seemed less enthused about Auckland, saying he was surprised by the low city "buzz" on game day in 2007 between Australia and New Zealand.

A keen Waikato rugby fan, who only wanted to be known as Peter, spotted a copy of Owens' auto-biography while out shopping. Peter's also a big fan of Owens and grabbed the copy of the book. He wanted to share some of the highlights with others waiting for the World Cup final to kick-off.

Peter discovered, through the book, the referee's appreciation for Hamilton and his humourous wit.

"He's a bit of a comedian, quite witty and is good at talking to the players - and the referee is so important these days," Peter said.

He believes Owens is the best referee to control the 2015 Rugby World Cup final.

"Absolutely, he's the right guy for the job. He's probably the most important man to New Zealand rugby this week," he said.

Peter agreed with Owens' comments on the now FMG Stadium Waikato.

"I like the stadium because you're close to the action and you can hear everything, all the talking on the field and the calls," he said.

The book was released in 2009, with Owen mentioning places he had travelled, thanks to his rugby career.

He said one of the advantages of being a professional rugby referee was getting the opportunity to visit many places in various parts of the world.

"Various places leave different impressions with visitors so, often with tongue in cheek, this is my take on the places."

Rugby fans have become use to Owen's direct, no-nonsense sense of humour during the 2015 Rugby World Cup.

The stand-up comedian, brought his comedic wit on to the field in the Scotland versus South Africa pool game where he called out Scotland fullback Stuart Hogg for his "hollywood" on a kick charge down.

The game was played on a football field, at Newcastle's United Football Club.

"Dive like that again and you can come back here again in two weeks and play. Not today. Watch out!"

The footage of the incident has been uploaded to the World Rugby YouTube channel and recorded nearly 500,000 views.
