He catapulted to worldwide fame in 2019 after his book, No Friend But The Mountains: Writing from Manus Prison, won the Victorian Prize for Literature, Australia's richest literature prize.
He wrote the book with WhatsApp on his phone.
Boochani's 374-page book, detailing his experiences in detention, was written in secret and was smuggled out of the detention centre via hundreds of text messages to his translators and editors in Australia.
Boochani discovered he had been granted asylum by New Zealand almost seven years to the day from the moment he was arrested by the Australian Navy, taken to Christmas Island, and subsequently flown to PNG.
Following the closure of the Manus Island centre in 2017, Boochani and his fellow detainees were moved to refugee transit centres near the island's main town of Lorengau, and later, to the country's capital Port Moresby.
The executive director of Amnesty, Meg de Ronde, said it is wonderful news that Boochani has been given asylum.
"This means that he's now a free man. He is free from the persecution as a Kurdish journalist. He's free from the persecution of Australia's torturous detention system and he is able to enjoy his life as anyone should be able to under our human rights system."
Last month the National Party said it was surprised New Zealand immigration officials didn't consult their Australian counterparts before granting a visa to Boochani.
The party's immigration spokesman, Stuart Smith, said Boochani appeared to have been excluded from Australia, making him ineligible to come to New Zealand without a special direction.
He said despite that, the response to a parliamentary written question showed no contact was made with Australian officials before he was granted the visa.
"Which was surprising given the high profile nature of Boochani and the fact that the Australian foreign minister said that Boochani would never set foot in Australia."
He travelled through the Philippines to get to Auckland so that his flight did not touch down in Australia.
