The effect on the woman of Hoko's offending was traumatic and Judge John McDonald jailed Hoko for eight years, with a minimum non parole period of 60 per cent of that.
The Court of Appeal found the sentence imposed was manifestly excessive.
It allowed Hoko's appeal and substituted the sentence of eight years' imprisonment with one of six years and six months' imprisonment. The minimum period of imprisonment of 60 per cent is to remain in place.
The court said Hoko has a very extensive list of previous convictions, including three for aggravated robbery.
In 1984 Hoko was sentenced to three years and six months' imprisonment for aggravated robbery. Also in 1984 he was sentenced to five years' imprisonment for aggravated robbery, concurrently with a sentence of eight years' imprisonment for rape.
In 1991 he was sentenced to seven years and six months' imprisonment for aggravated robbery.
"Mr Hoko's offending in this case appears to have occurred after the break-up of a long-term relationship, resulting in a return to his former pattern of anti-social behaviour," the Court of Appeal judgment said.
"The starting point should have been six years' imprisonment with an uplift of six months, resulting in an end sentence of six years and six months' imprisonment."
