Abstract: Purpose - This study aims to provide a snapshot of voluntary sustainability assurance in New Zealand (NZ) in 2020. we assess the frequency of different assurance elements and discuss aspects of current practices that potentially contribute to the audit expectation gap. we also test whether the determinants of voluntary sustainability assurance in NZ are consistent with international findings. Design/methodology/approach - For 118 companies listed on the New Zealand Stock Exchange in 2020, we hand collected data on whether sustainability information was assured, subject matter assured, assurance level, outcome, provider, disclosure of detailed procedures, standard referenced and criteria applied. we then examine the influences of voluntary sustainability assurance using both univariate and regression analysis. Findings - Approximately 20% of listed companies that disclosed sustainability information provide a sustainability assurance report, indicating low levels of assurance compared to international practices. we note that the presence of different forms of assurance and certification, placement of sustainability information before financial statements and the associated audit report and mixture of assurance levels potentially contribute to the audit expectation gap. Further, voluntary sustainability assurance practices are diverse, and there are notable differences between Big Four accounting firms and other providers in terms of assurance level and standard referenced. Consistent with prior studies, we find size and industry classification as two main drivers of voluntary sustainability assurance. Originality/value - We contribute NZ-specific insights to the sustainability assurance literature. The findings on voluntary sustainability assurance practices and reflection on the audit expectation gap are timely and relevant to the new climate-related disclosure mandate and pending assurance requirements.
