When adults who have sexually abused have contact with tamariki or rangatahi

We need to assess and understand what safety measures are in place to protect te tamaiti or rangatahi to minimise the risk of further opportunities for sexual abuse.

Upcoming changes for this guidance

This content will be strengthened so it more completely reflects our commitment to practice framed by te Tiriti o Waitangi, based on a mana-enhancing paradigm for practice, and drawing from ​Te Ao Māori principles of oranga to support mana tamaiti, whakapapa and whanaungatanga. We each need to consider how we can apply these principles to our practice when reading this guidance. The following resources provide support:
Practice for working effectively with Māori
Our practice approach


We undertake an assessment if an adult has been accused of sexual abuse, regardless of whether they have been charged, convicted or admitted the allegations.

People who sexually abuse are not from a homogeneous population. There are no set criteria to determine who poses a risk of sexual offending against tamariki and rangatahi.

How we undertake the assessment

Our assessment isn’t just focused on the alleged offender and their access to or relationship with te tamaiti or rangatahi, but includes the whole whānau or family as a unit.

There is shame and stigma attached to allegations of child sexual abuse. Therefore, we approach our assessment sensitively and use language carefully, to focus on safety.

We work with whānau or family, the alleged offender and specialists in the community to find ways to identify and stop harmful or potentially harmful behaviours from continuing. We focus our assessment on understanding the relational dynamics in the whānau or family.

Our assessment needs to consider:

  • the response of the whānau or family – it is normal for them to be shocked and angry, and even disbelieve the allegations, and they may appear non-protective – however, it is important we don’t judge or label
  • if there is any evidence of ‘grooming’ and its impact on everyone – the victim, parents, siblings, and any other whānau members
  • how we provide support and information, and allow time to help them process the situation by focusing on the facts, including any indicators of abuse or behavioural distress
  • the attitude and knowledge of everyone in the whānau or family and networks
  • how the beliefs of the whānau or family relating to gender (male and female) and roles (adult and child relationships) contribute to safety or harm
  • any evidence of adults engaging with tamariki and rangatahi around respectful relationships – what does respect look like in this whānau or family?
  • who in the whānau or family is responsible for the day-to-day care and how supported they are
  • who tamariki and rangatahi rely on when they are not feeling safe, heard or listened to
  • how shame, stigma or stress is managed within the whānau or family
  • how connected or isolated the whānau or family is to wider whānau or family, community, church, etc
  • other types of violence, behavioural concerns or indicators that are occurring, such as financial or psychological abuse
  • if we can identify a sustainable commitment within the whānau or family to keeping tamariki and rangatahi safe from any future harm and to healing, despite the abuse being denied.

Research indicates that sexual abuse can occur across generations. Use chronology and genograms with key members of the whānau or family to understand patterns of trauma or abuse impacting the whakapapa of the whānau or family over time – we need to use these tools carefully, be sensitive to the mana of the tamariki and whānau or family, and be mindful that the sexual abuse may trigger further impacts for other whānau or family members who have experienced sexual abuse themselves.

When someone has admitted, received treatment or been convicted for sexual abuse

Our assessment will explore how their treatment or safety plan is being followed and any risks are being managed. We work closely with them, their whānau or family, their treatment providers, any other professionals involved and the Probation Service.

We maintain the mana of all involved by not just focusing on the abuse but on what the person and their whānau or family or support network is doing differently to keep everyone safe from any further harm.

Our assessment needs to understand the risks and identify what safety looks like over time and to support the oranga of the whānau or family. Consider:

  • whether or not they have engaged in treatment or a therapeutic response
  • if they attended treatment, did they complete the recommended programme, how long ago and have ever adjusted their safety plan to reflect a change in circumstances
  • if the recommendations in their safety plan have been followed
  • who in their network or whānau or family knows about their history and how they are helping them to maintain safety – abuse generally happens in secrecy.

When someone has denied they have been sexually abusive

We use the Child Protection Protocol (CPP) for cases that require an investigation response, working in consultation with the police. If the CPP criteria are not met, we use the decision response tool to determine what our approach will be.

A person who has been accused does not have to admit they have been sexually abusive for us to undertake an assessment. ‘Denial’ may be a factor that we incorporate into our assessment and planning.

An assessment needs to include an understanding of grooming behaviours. The reality is that less than 10% of sexual abuse against te tamaiti or rangatahi is committed by a stranger. Therefore the likelihood is that sexual abuse occurs after a period of grooming by someone known to te tamaiti or rangatahi and their parents or caregivers.

Grooming is when someone builds a relationship, trust and emotional connection with te tamaiti or rangatahi so they can manipulate, exploit and abuse them. Someone who is sexually abusive can also groom other siblings, parents or caregivers to ensure access to te tamaiti or rangatahi.

Grooming behaviours can be methodical, subtle, gradual and escalate over time to include abuse. The grooming behaviour can be so subtle that at times, victims/survivors and even their caregivers can believe the abuse was their own fault or that they caused the abuse to happen. Potentially, we can also be groomed into not believing tamariki or rangatahi when they speak or their behaviour indicates distress, labelling them as acting out or naughty. Often, evidence of child sexual abuse is the word of te tamaiti or rangatahi against an adult.

Netsafe provides information we can use when talking with tamariki, rangatahi and whānau or family about grooming that can occur online.

Reflect on how the dynamics of sexual abuse impact not only on the whānau or family but also on our own practice response and decision-making. Test for confirmation bias through supervision or case consults. Include professionals who specialise in the sexual violence field to help evidence our assessment.

When tamariki or rangatahi disclose

Child sexual offenders often select tamariki or rangatahi who are already vulnerable and will not be believed if they speak out.

Disclosure of abuse can be a process and not a one-time event. It is not uncommon for tamariki to retract their allegation, especially when the adults around them respond in the way the abuser has said – for example, ‘I will get in trouble’, ‘you will be taken away’, ‘your mum will be mad/sad/etc’.

Research shows that almost all survivors/victims stated that they knew their offender and over 60% of tamariki and rangatahi who had experienced sexual abuse did not disclose the experience to anyone.

Tamariki or rangatahi rarely lie to get into trouble. If a tamaiti or rangatahi does not repeat their disclosure in a specialist child interview, we continue to assess by considering the indicators of abuse.

Sexual abuse

Even when we determine that the sexual abuse was unlikely, the disclosure is evidence that something is not right for te tamaiti or rangatahi. Our assessment needs to consider their age and developmental stage in relation to their sexual knowledge and behavioural distress. We focus on understanding what is happening for te tamaiti or rangatahi and consider what intervention will help them.

Our assessments need to find ways to strengthen protective relationships around tamariki and rangatahi.

Language and labelling

Our recording needs to be factual. 

If someone has been accused of sexual abuse, then it is important that we are clear not to label them incorrectly. We use the person characteristic to accurately record any findings attached to individual people, and we make sure we update it. 

An adult can be a child sex offender as well as a victim or survivor of sexual abuse themselves. Be mindful to name the behaviour and the impact rather than label the person.

Some people identify as a victim, while others prefer the term survivor. If both terms are applicable, for recording purposes, ‘victim’ can be used when referring to someone who has recently been affected by sexual violence, while ‘survivor’ can be used to refer to someone who has gone through the recovery process. However, the best way to be respectful is to ask for their preference.

For a person who has been convicted, record the conviction rather than refer to them as an ‘offender’.

Paedophilia is a psychiatric disorder that describes a sexual preference towards prepubescent tamariki. We only record ‘paedophilia’ if there has been an official psychiatric diagnosis as defined by the Diagnostic and Statistical Manual of Mental Disorder (DSM-5). Research shows that not all people who sexually abuse tamariki are paedophiles and not all paedophiles go on to sexually abuse tamariki. Even if whānau or family or people in the community use this language, we are careful about what we record.

We never record someone under the age of 18 as a child sexual offender, even if they have been through the youth justice system.

Concerning or harmful sexual behaviour

Intervention and treatment, and responding to adults who have sexually offended

Violation against other people or a whānau or family member is viewed as a significant breach of sacred relationships and wellbeing. Most Māori and Pacific communities will try to re-establish the disrupted relationship and restore balance. Studies have identified the importance of addressing violence holistically, rather than focusing on 1 type of violence.

Consider interventions that create behaviour changes that are integrated and holistic, combining mental and physical health, disability, violence, safety, and alcohol and drug rehabilitation.

Our responsibility is to work with whānau or family and the community and represent the voice of tamariki and rangatahi to support them to create their own enduring safety and healing from abuse.

We can only represent the voice of tamariki and rangatahi if we include them in building safety along with whānau or family members and other professionals.

Research has found that child sex offenders who have completed a treatment programme in New Zealand are less likely to be charged or reconvicted for a sexual offence than an untreated child sex offender.

The Department of Corrections provides treatment for child sex offenders at:

  • Kia Marama at Rolleston Prison (Christchurch)
  • Te Piriti at Auckland Prison.

Treatment providers

There are 3 main community-based treatment providers. Intervention is tailored to meet the needs of individuals.

SAFE (Whangarei, Auckland and Hamilton)

WellStop (Wellington, Masterton, Manawatu, Whanganui, Levin, Hawke’s Bay and Gisborne)

STOP (Nelson, Christchurch, Invercargill and Dunedin)

Even if the treatment provider isn’t in your region, contact the closest provider for advice.

Child Sex Offender Register

People who are convicted of a qualifying child sex offence are registered on the Child Sex Offender Register once they’ve served their sentence. They remain on the register for 8 or 15 years, or for life, depending on the offence.

Police case managers assess registered people for their risk of sexual reoffending and support them to participate safely in their communities (for example, maintain relationships with whānau or family, gain employment, develop ties to the community, and access treatment) as this reduces their risk of reoffending.

When we have contact with a registered person, we should engage with the Police case manager, who will:

  • provide information about the risk presented by the registered person
  • work with us to mitigate those risks
  • help us understand what information needs to be shared with others to keep tamariki and rangatahi safe.

Reporting of sexual abuse is very low in New Zealand, which leads to extremely low rates of conviction and therefore registration. For this reason, we do not just rely on the register – we listen to what tamariki and rangatahi are saying and showing us through their behaviours.

Requesting information

We should contact the Police case manager directly if we know who they are.

If we don’t know who the case manager is, or don’t know if the person is registered, we should email a section 66 information request to the Police.

Requesting information

Disclosing information

We need Police approval before we can share information provided by the register with an ‘affected person’ (such as a parent, teacher or regular caregiver). Register information can only be disclosed if the Police case manager believes that the registered person is a threat to the life, welfare or sexual safety of a specific tamaiti and rangatahi.

If approval is given, the Police will most likely make the disclosure, in conjunction with the Oranga Tamariki social worker. The affected person will have to sign a confidentiality agreement.
