Pauline Kay Hanna (21 February 1958 – April 2021) was a New Zealand woman who was found dead in her home in Remuera, Auckland that she shared with her husband, Philip Polkinghorne, on 5 April 2021. The circumstances of her death attracted significant media attention after Polkinghorne was accused of murdering her and staging the death as suicide by hanging.

Background

Pauline Kay Hanna was born on 21 February 1958, and was raised on a farm in Havelock North, Hawke's Bay, New Zealand. She studied at the University of Otago and received a master's degree in business administration.

At the time of her death on 5 April 2021, Hanna was married to eye specialist Philip Polkinghorne. She was also as an executive project director at the Counties Manukau District Health Board, where she had worked in several roles since 1998. She also lead Auckland's COVID-19 supply chain at the time of her death. The couple met through work with Hanna becoming step-mother to Polkinghorne's three children from his first marriage. According to Polkinghorne, Hanna had a good relationship with her step-children and had a grandson.

According to Polkinghorne, Hanna had worked through the 2021 Easter holiday weekend but the couple were able to spend time together on Easter Sunday (4 April). The couple visited Highland Park where Hanna visited a vaccination station before having lunch together and returning to their Upland Road home in Auckland's Remuera suburb. Polkinghorne also said that the couple had dinner together before watching television. Before going to bed, Polkinghorne also said that Hanna had helped him to write a letter. According to The New Zealand Herald, Hanna was still sending work emails at 10pm on Sunday night.

Death and aftermath

On 5 April 2021, Polkinghorne said that he had found his wife Pauline Hanna dead in the early hours of the morning. While preparing to make her breakfast at 7:00 am, Polkinghorne said that he found Hanna dead. Polkinghorne's sister said that she and Polkinghorne had found Hanna on the ground covered by a duvet. There were two pieces of rope hanging from the balustrade and the staircase. Polkinghorne late told Hato Hone St John emergency responder Hannah Matheson that a 111 operator had told him to "cut her down." According to Matheson, Polkinghorne said that his wife was suffering from depression but was unaware of what medications she took. Matheson also noticed that Polkinghorne had a fresh graze on his forehead, which he claimed to be unaware of.

During an interview with The Weekend Herald published on 10 April, Polkinghorne denied there were problems with their marriage and said that he was unaware of her state of mind at the time. He also suggested that Hanna was affected by her mother's death six weeks earlier. Polkinghorne also said that he "believed she was overworked but she was extremely highly regarded by her work colleagues." Polkinghorne also ruled out an intruder entering their home. He described the loss of his wife as "insurmountable" and claimed their relationship was "perfect." Pokinghorne also told The Herald that Police were treating him as a person of interest. On 15 April, Hanna's funeral was held at the Holy Trinity Cathedral in Parnell, which was attended by her family, friends and colleagues including her husband Polkinghorne.

Investigation

Shortly after arriving at the house, police detective constable Christian Iogha performed a "tension check" on the orange nylon rope tied to the handrail at top of the stairs that Hanna had allegedly hung herself with, to confirm that it could handle the weight of a body. He gently tugged the rope, and it quickly began unravelling. Detective Ilona Walton, who witnessed the check, later testified that "it seemed unusual and not normal that the rope would unravel in that manner", and she informed her sergeant. Iogha examined the rope again and became suspicious after noticing that it had not been pulled to the base of the handrail by Hanna's weight during the suicide. Polkinghorne, who was giving a statement to the police in the house, was asked to continue outside so that the scene would not be contaminated.

Soon after the test was conducted, police decided to treat the case as suspicious. Polkinghorne was taken to be questioned at the Auckland Central Police Station, where Walton conducted a three-hour interview with him. During the interview, he recounted finding Hanna's body and repeatedly spoke off-topic. The New Zealand Police remained at the home for nine days, performing forensic searches and extensively sampling for DNA and stains found in the house. Hanna's bedroom was found dishevelled, with what appeared to be a blood stain on the bed, though no evidence was found that her body had been moved from the room to the spot it was initially found. Police found a drug pipe, lighter, and 37.7 grams of methamphetamine throughout the house, with Polkinghorne's DNA found on the containers. They also found a belt in the kitchen with a pattern that corresponded with the distinctive markings found on Hanna's neck.

On 6 April, Dr. Kilak Kesha performed a post-mortem examination on Hanna. He observed several injuries on her body, including abrasions on her nose and back, haemorrhages on her face and fresh bruises on her arm that he believed indicated she had been grabbed. Ligature marks were found on her neck. Her tongue was protruding, which he noted often happened during hanging suicides. A low level of alcohol and high amounts of unprescribed zopiclone sleeping pills were also found in her system. From the examination, he determined that Hanna had died as a result of strangulation, though was unable to determine whether or not the death was self-inflicted.

In May 2021, Police confirmed that traces of methamphetamine had been found at the couple's Upland Road residence. By April 2022, the Police confirmed that detectives had interviewed several of Polkinghorne's associates including a masseuse and a barber. Newshub also reported that Hanna had hired a private investigator prior to her death, and that Polkinghorne had been in a relationship with an Australian escort for several years.

Trial

Polkinghorne was formerly charged with the murder of Hanna in August 2022, sixteen months after her death in April 2021. He made his first court appearance in the Auckland District Court on 16 August, and pleaded not guilty to the charges. He was released on bail by Judge Andrea Manuel whilst awaiting his trial. He made an appearance at the Auckland High Court on 31 August, and his trial was scheduled.

His trial began on 29 July 2024 at the Auckland High Court, before Justice Graham Lang and a jury. His lawyer in the trial was Ron Mansfield KC, and the prosecutor was Crown Law Office solicitor Alysha McClintock. The prosecution case was that Polkinghorne's marriage to Hanna had deteriorated, and he had strangled her and staged the death as a suicide. McClintock argued in her opening statement that he was spending considerable amounts of money on sex workers and methamphetamine, the latter of which had made him behave aggressively and angrily. The defence counter-argued that Hanna had made previous suicide attempts and struggled with mental health issues, and that her death was a suicide. Mansfield argued that the couple's relationship was stable, and that Polkinghorne's use of methamphetamine was "casual". He pleaded guilty to possession of methamphetamine and a pipe, but denied murdering Hanna.
