Wellington man Michael Preston, jailed for the murder of his estranged wife, Mei Fan, is appealing his conviction.

The 60-year-old was sent to prison for a minimum of 19 years earlier this month, having previously been found guilty by a jury of Ms Fan's murder.

He was also found guilty of a second charge of breaching a protection order.

An appeal was lodged on Friday, though a hearing will likely still be months away.

Ms Fan was killed in her Miramar home in November 2013 after dropping her two children at school.

She was stabbed a number of times in a frenzied attack, which was described as a "deeply personal" killing by sentencing judge Justice Joe Williams.

The Crown contended Ms Fan's murder was the culmination of a toxic relationship and was to do with custody of the pair's children.

Ms Fan took out a protection order the day before she died.

The defence suggested the death was a burglary gone wrong, while Preston proposed a number of other people could have committed the crime.
