As with ACC decisions for other types of claims, you can appeal to an independent reviewer if ACC turns down your claim for mental harm caused by sexual abuse. For example, if ACC‘s assessor decides there’s not a strong enough causal link between your mental condition and the abuse you suffered, you can challenge that on appeal. You can also appeal if ACC accepts your claim generally but refuses you a specific form of assistance like lump-sum compensation. For more details, see “Challenging an ACC decision”.
