Philip Polkinghorne must wait at least three more days before a jury rules him innocent or guilty of killing Pauline Hanna.

The jury has gone home after telling the judge they couldn't reach a decision today - having deliberated since 11am.

They won't sit tomorrow because of a juror's prior commitment and will recommence 11am on Monday.

The Herald's Michael Morrah has been in court.

He says Polkinghorne reacted emotionally this morning as the 111 call after Hanna died was replayed for the jury.

"He was so upset that the judge has to call for the proceedings to be put on hold, essentially."
