Brendon O'Connell was jailed in 2011 over a racial attack and has apparently failed to claim political asylum in New Zealand.

A blogger previously jailed in Australia over a racial attack has tried to enter New Zealand and wound up in custody.

Brendon O'Connell, 46, is an outspoken critic of Israel and what he describes as "Zionist power."

Now the Australian man is in New Zealand, where it's understood he fled for political asylum but ended up under arrest.

Immigration NZ confirmed that O'Connell had been detained at the border.

"This individual had his entry permission to New Zealand revoked on character grounds and is now in custody," a spokesperson said.

It's not yet clear where he's being held. The Corrections Department has declined to comment.

O'Connell is a proponent of conspiracy theories related to a Jewish elite. In a recent video on his website, he blamed this month's Las Vegas shooting on an "Israeli kill squad."

In 2011, the 46-year-old was sentenced to three years in jail in Australia after being found guilty of six racial hatred charges.

The charges related to a the posting of a verbal altercation he had with Stanley Keyser and Timothy Peach, who are Jewish.

An argument broke out between the three men at an IGA supermarket in South Perth in 2009, where a Friends of Palestine group was holding a protest against Israeli oranges.

O'Connell was using a video camera at the event and in a video he later posted online, he labelled Keyser a "racist, homicidal maniac."

At sentencing, the judge said O'Connell showed no remorse and his behaviour "was that of a bully".

O'Connell's Twitter bio currently describes him as being "on the run."
