Letters from Samoa's Prime Minister, the Speaker of the House and police chief described Seti as a "great asset to Samoa", and said his absence had already been heavily felt.
The PM's letter asked the judge to be lenient: "I pray for a more lenient sentence that may allow him to return to Samoa as has been the practice by the courts in the past."
But Judge Fraser said during sentencing that Seti fleeing to Samoa was an aggravating factor.
"Trial was delayed by many years with the need for extradition and the delay has been highly impactive on the complainant."
He said rape was always a serious, violent offence. "The psychological impact of this offending will stay with the victim probably for the rest of her life."
The judge said the complainant had accepted a ride home about 2am after a night out in September 2005, and ended up sleeping in Seti's bed. About 7am she woke to find Seti having sex with her.
She told him "No" and to get off her. "You then got off her without a word and went and lay on a nearby couch," the judge said.
The complainant, now 28, said after the incident she had self-harmed, began drinking a lot and got into trouble with the police. Seti's lack of remorse had made it difficult to start the healing process, she said.
"I've been living with this for the last nine years and I was finally able to see justice done."
In sentencing, Judge Fraser took a starting point of six years, added an uplift of seven months for Seti fleeing, a discount of four months for the time spent on electronic bail, and six and a half months for remorse and good character. He said Seti would likely be extradited back to Samoa after his release.
Outside court, defence lawyer Shane Tait said Seti was arrested two days before he was due to fly to New Zealand to hand himself in. Asked why he had avoided facing the charge until then, Mr Tait said it was "just head in the sand for a few years".
