Macsyna King's sister has denied she made up a story only in the past two weeks to explain why cellphone records showed the pair in the area the evening Chris and Cru Kahui were fatally injured.
Macsyna was confronted with the cellphone evidence in the High Court at Auckland trial of Chris Kahui, charged with the murders of their twin sons.
The crown alleges Kahui fatally injured the twins on June 12 2006 in their South Auckland home, while defence lawyers say someone else, probably Macsyna, hurt them.
Emily King, the younger sister of Macsyna, denied she only remembered getting a phonecall from husband Po Hepi on the night the twins were hurt after police asked her about it two weeks ago.
The evidence, from an at times emotional Ms King, came as it was revealed her husband had refused to give evidence for the crown, despite a summons to do so.
Police were trying to trace him.
Ms King has been acting as a go-between between her husband and police. She has made it clear her husband was not happy at being called as a witness and would not do so.
Defence lawyers say mobile phone records proved Macsyna had returned to the house where the twins were hurt, rather than driving with her sister to a friend's home in West Auckland.
Ms King described to the court the journey she said the pair took from South Auckland to West Auckland that evening.
Ms King, a painter from South Auckland, said as they were driving to West Auckland she got a phonecall from her husband asking her to bring their four-wheel-drive home .
Under cross-examination she was asked why in several statements to police since the twins' death in June 2006 she had not recalled getting an angry phone call from a "pissed off" Mr Hepi.
Defence lawyer Michele Wilkinson-Smith said in several statements Ms King had been able to recall many details, including what she had eaten that evening, but at no stage did she mention receiving an angry call from her husband.
Ms King said it was not possible to remember every detail and the events had happened a long time ago, but once her memory had been jogged she was able to recall more details, including the phone call.
Ms Wilkinson-Smith asked if it was true that in a statement to police on March 1 2007, when asked specifically by two police officers at her house about the cellphone record, Ms King could not account for the phonecall from her husband.
"I put it to you that you've not been truthful about your movements."
Ms King replied that she had no comment, but denied her sister had taken her car and returned to Mangere.
Ms Wilkinson-Smith told Ms King she had come up with the explanation about the phonecall from her husband only after her sister was confronted with the cellphone records during cross-examination.
Ms King said she remembered the phonecall after her sister had given evidence, and after she visited her sister at the hotel she was staying at when giving evidence.
"Your husband is refusing to give evidence?" Ms Wilkinson-Smith asked.
Ms King replied "You would have to ask him."
"We would love to, can I ask where he is?"
"Not right now," Ms King replied.
Ms King earlier said police asked her to remember the route the pair drove the evening the twins were fatally injured, because of allegations of a conspiracy theory.
"I was told to remember (the route) because there was going to be some sort of conspiracy that I was making it up for my sister.
"I needed to be clear about the route I travelled that night."
The trial continues tomorrow.
