When he overheard his colleague's request, he approached Patient X, who came inside.
Mr Takataka then swore at the patient for being outside and not coming in when asked and shouldered the patient, who walked away.
Mr Takataka closely followed the patient while swearing at him saying "don't you f****** pull this f****** shit on my shift" and "you need to learn".
Mr Takataka was told by his senior colleague to leave the patient alone.
Patient X then stopped, turned towards Mr Takataka and told him to "f*** off", which resulted in Mr Takataka physically forcing him to the ground and holding him in a head lock.
Mr Takataka was told by three co-workers to get off the patient and had to be pulled off him.
Following the incident, Patient X laid a complaint of assault.
Mr Takataka was suspended on March 6 while the WDHB conducted its investigation, and on April 8 he was summarily dismissed for serious misconduct.
Mr Takataka accepted he swore at Patient X, but said he had only done so because the patient had sworn at him and he was talking to him on the "same level".
He denied being the aggressor and claimed he followed the patient to ensure he was ok.
He said he only "took down" Patient X when he became isolated and was attacked.
While there were a few variations in witness' statements, the WDHB concluded the incident occurred largely in the way described by the witnesses and Patient X, and not in the way described by Mr Takataka. The authority concurred.
Employment Relations Authority member Anna Fitzgibbon said the dismissal of Mr Takataka by the Waikato District Health Board was justified.
