The court heard Rewiri, who was in prison at the time of the attack, gained access to a cellphone and contacted Neketai, requesting he collect a debt of more than $30,000 from Mr Kimura.
The Crown alleges Neketai attacked Mr Kimura after Hiku lured him from his house. Neketai is accused of punching Mr Kimura so hard he fell backwards, hitting his head on a concrete driveway, before kicking him in the face, possibly more than once, causing massive head injuries.
Mr Kimura was found lying face down on the concrete at the bottom of some steps in a pool of blood by his wife, Rosina Kimura.
The jury has heard his injuries included a fracture to the left side of his skull that extended along the side of his head to the left eye socket, and extensive bruising and swelling to his face.
Mr Kimura died six weeks later in Tauranga Hospital on his 44th birthday.
Justice Brewer suppressed the reasons why the charges were reduced to manslaughter for two of the accused and has barred publication of the reason why Mr Hartley was discharged.
Rewiri will be sentenced in the High Court at Hamilton on August 16.
Hiku and Neketai have chosen not to call evidence, and the trial was to continue today with closing addresses by their lawyers and the Crown. Those would be followed by Justice Brewer's summing up before the jury would retire to consider its verdicts.
