A Christchurch woman found guilty of murdering her husband is to appeal her conviction.
In December last year, Helen Milner was convicted of murdering her husband Philip Nisbet in 2009 and of one charge of his attempted murder.
She was sentenced to life imprisonment with a minimum non-parole period of 17 years.
In his sentencing, Justice Gendall said it was a carefully planned murder out of which Milner stood to gain financially.
He said she poisoned Mr Nisbet with an overdose of an antihistamine to which he was allergic in order to get his $250,000 life insurance payout
Mr Nisbet's death was initially treated as a suicide, but an investigation into his death was reopened after concerns were raised by his sister.
No date has been set for the appeal.
