The 29-year-old tour guide from Krakow travelled to New Zealand at the end of November to try to become a goblin extra in the filming of the forerunner to the Lord of the Rings.
An avid fan of the books - he has read them 20 times in four languages - Sir Peter Jackson's movies and a speaker of Elvish since high school, Mr Osika has not been able to become an extra, due to problems obtaining a New Zealand work visa.
"Until February, I can't do anything officially, but if I know I'll be an extra I can get my forms done on February 15, I can get my visa and then I am ready to goblin," Mr Osika said with a grin.
While filming of The Hobbit takes a break, he is making the most of his respite from marauding the streets of Wellington by touring southern locations used in the film trilogy.
The tour of the South will take him to Te Anau, Doubtful Sound and Twizel, before he returns to Wellington.
He hopes the publicity caused by his "goblining", with recycled scrap metal armour, boot polish and contact lenses, will catch the eye of Sir Peter Jackson and his team.
In the meantime, donations to his goblin's treasure chest are helping his trip along.
