ERA member Rachel Larmer dismissed Wikaira's claim the department breached the Employment Relations' Act by issuing her with a preliminary decision before it met with her. Ms Larmer ruled the department's operations support manager Michal Rongo genuinely considered her explanation and weighed all the evidence before deciding to dismiss her.
Wikaira claimed she acted in self-defence which gave rise to the wilful damage charge but Ms Larmer said that position was open to her to run in the District Court but she chose to plead guilty.
Despite signing an acknowledgment of receipt of a criminal charge and summons on February 13, Ms Larmer said Wikaira claimed she was not aware she had been charged with until March 11.
"Why attend court and instruct a criminal lawyer if she was not aware she had been charged with a criminal offence?," Ms Larmer said.
"Given the nature of Ms Wikaira's role as a corrections officer and the nature and environment of the department, the failure to disclose a criminal charge at the earliest opportunity is conduct which is capable of being viewed as serious misconduct. It goes to the heart of trust and confidence for someone in her position."
