The ex-husband of Massey librarian Jennifer Yang has been found guilty of murdering her in a frenzied daytime West Auckland stabbing.
Jurors at the High Court in Auckland reached a verdict on Tuesday morning.
The courtroom was silent as the verdict was read out and Justice Pheroze Jagose entered convictions as Manchao Li stood in the dock.
The Crown had argued Li, 65, was obsessed with revenge after breaking up with his wife and getting swamped in a decade-long legal dispute over money and property.
Defence lawyers argued Li was not in the right frame of mind to form murderous intent. Li said he could not remember the stabbing. He will be sentenced on December 18.
