Auckland's High Court has heard from those first on scene - where Pauline Hanna was found dead.

Auckland eye surgeon Phillip Polkinghorne is accused of killing Hanna at their Remuera home in 2021.

The defence says she took her own life.

ZB reporter Chelsea Daniels is attending the trial.

She says the court's heard about Polkinghorne's immediate reaction after Hanna's death.

"St John paramedic Hannah Matheson was one of the first ambulance members at the scene - she told barrister Brian Dickey that as she was asking him questions about the morning's events, he seemed calm."
