"Signed, sealed, delivered ... got the paper, off the hook!!!" he wrote, adding details would follow later.
His father, Trevor Hastie, told the New Zealand Herald he received a phone call from his son earlier today with word the nightmare had come to an end.
"All charges have been dropped," said Mr Hastie.
"He's a free man."
Mr Hastie said his son told him he would be tending to business affairs in Cambodia before heading back to New Zealand for a holiday.
He said the latest development came as a complete relief after a harrowing six months since he was taken into custody.
"It really is the best news we all hoped for," said his father.
"He told me "it's a monkey off my back".
It is unclear if his co-accused Eglitis was freed from charges.
The fugitive is wanted in Australia on kidnapping and torture charges.
Eglitis fled Australia on the eve of being committed to stand trial in Brisbane in 2007 after a magistrate ruled there was enough evidence to potentially convict him of attacking businessman Ronald Sydney Ryton-Benson.
He faces outstanding charges of kidnapping, deprivation of liberty, robbery, impersonating an officer and possessing restricted items.
It was thought at the time his court appearance in Cambodia could trigger his extradition back to Australia.
