In the fight, Mr Hollick suffered from stab wounds to the neck, and later died.
The Nacka District Court was critical of the initial investigation into Mr Hollick's death, Swedish media reported.
The court said it believed the investigation was incomplete, inaccurate and unclear, as Thai police did not carry out any detailed crime scene investigation and did not hold any formal hearings.
A knife, which was suspected to have been the murder weapon, also disappeared.
Due to these "flaws" in the investigation, the Nacka District Court was unable to charge the man with murder.
Before his death, Mr Hollick owned Top Dog personnel, a company that provided earthmoving workers to Western Australian mines.
He was semi-retired and had moved to Thailand, a Top Dog worker said.
His Old Friends profile said he grew up in Upper Hutt, attending Upper Hutt College before working in the Upper Hutt Post Shop.
After a year there he moved on to BNZ Upper Hutt and then from 1993 to 1999 he worked in "various weird and wonderful jobs".
In 2000 Mr Hollick got involved in recruitment work, before opening his own business - Top Dog Personnel - in 2005.
He was not married and did not have any children.
In 2012, his elderly mother said she was shocked to hear of her son's death, and said she hated him being "over there" in Thailand.
The Nacka District Court also ordered the man to pay $30,000 SEK ($4597 NZD) in damages to the Mr Hollick's family.
