A woman has been charged in relation to the death of Te Atatu pensioner Cun Xiu Tian, police say.

The 43-year-old woman has been charged with accessory after the fact to burglary.

She will appear in the Waitakere District Court on Wednesday next week.

A 19 year-old man previously charged with murder and sexual violation in relation to Ms Tian's death is due to reappear in the High Court at Auckland the same day.
