NZ whistleblower granted bail, NZ Gov screams "misinformation!"

Some pretty amazing quotes from this.
We take the security of our data very seriously and are extremely disappointed at this gross breach of trust by this individual and his alleged involvement in spreading harmful misinformation.
Speaking to media this morning, Labour leader Chris Hipkins said the breach was worrying. “I am pretty concerned about the momentum building behind some of these conspiracy theories. They’re not grounded in fact.”

If this was a legit and serious data breach, then this is not “misinformation”. If this is “misinformation” and fake, then it wasn’t a serious data breach and no crime was committed. So which is it?
