The woman accused of Helen Gregory's murder in the Wellington suburb of Khandallah has pleaded not guilty.
The 79-year-old was found dead in her Baroda Street home in January after what police called a "violent act".
A 52-year-old woman, whose identity is suppressed, faces one charge of murder and one of obtaining thousands of dollars by deception.
She remains on electronically monitored bail.
A trial date had been set for early next year, but the Crown has asked for a postponement due to scheduling conflicts, which could mean a delay until 2026.
Gregory's obituary, published in The Post, said she was a dearly loved mother, mother-in-law and treasured grandmother.
