A coroner has told an inquest into the death of the Kahui twins that it is time their father gave straight answers to straight questions.
Three-month-old Chris and Cru Kahui died after being admitted to a children's hospital in Auckland in June 2006.
The boys' father, Chris Kahui, was acquitted of their murder following a High Court trial in 2008.
Coroner Garry Evans has repeatedly asked Mr Kahui why he decided against calling an ambulance when one of the babys stopped breathing.
Mr Kahui has so far been unable to answer that question but has conceded that, had the twins' mother been home, she probably would have.
Mr Evans asked Mr Kahui why he failed to act like a normal parent and told lawyer Chris Wilkinson-Smith that it was time his client gave "straight answers to straight questions".
Mr Wilkinson-Smith told the coroner his questions have not been straightforward and his client needs more time than most to formulate his answers.
