An early childhood teacher who was arrested after a recording device was found in a staff bathroom now faces 21 more charges of making an intimate visual recording.

Police say no children have been identified in any of the recordings.

In response to earlier questions from RNZ, Detective Senior Sergeant Natalie Flowerdew-Brown confirmed police received a report that a recording device had been found in a staff bathroom at an early childcare education facility in Mount Maunganui on 30 June.

"Police conducted enquiries and a 53-year-old man was arrested in relation to the incident.

"He is due to reappear in Tauranga District Court on 3 August, charged with making an intimate visual recording."

The man appeared in the Tauranga District Court on Monday. A registrar confirmed to RNZ he had been granted interim name suppression and was placed on bail until his next appearance in September.

The man now faces an additional 21 charges of making an intimate visual recording.

Police confirmed on Monday the new charges relate to alleged recordings of adults.

RNZ has seen an email that has gone to parents from the early childhood centre on 6 July.

The email said the staffer, a full-time teacher, was arrested on 2 July.

"The matter remains the subject of an ongoing police investigation and we have been advised that this will take some time. We are fully cooperating with that police investigation.

"While the investigation is continuing, we do not know the full extent of the matter."

The email said all appropriate safety checking, including regular police vetting of the staffer, was undertaken.

"We know for some of you that this will come as a shock as he was a popular member of [the] team and well thought of by colleagues."

The Teaching Council register confirmed the teacher had voluntarily agreed not to teach.

Ministry of Education spokesperson Tui Rolleston earlier said the ministry was "supporting the service as needed".

"Given there is an ongoing police investigation it would not be appropriate to comment further."

Teaching Council chief executive Sean McKinley earlier said in a statement to RNZ that the safety and well-being of children and young people was "paramount to the Teaching Council".

"We can confirm that the Teaching Council has received a report regarding this teacher. Safeguarding learners is at the heart of the Teaching Council's role.

"When we receive information that raises concerns about a teacher's conduct or fitness to teach, we assess that information and consider what protective measures may be required under our statutory processes. These processes are designed to protect learners, prevent harm, and maintain public confidence in the teaching profession."

McKinley said that in general the Teaching Council was unable to provide information on complaints or Mandatory Reports that have been made to the Council.

"We take serious care with these matters as at the end of the day our priority is keeping Aotearoa's learners safe. We encourage anyone who has any concerns about a teacher to reach out to us."
