Abstract

Purpose

The purpose of this study is to examine the effect of internal audit function (IAF) use on earnings quality and external audit fees using empirical data collected from the New Zealand (NZ) setting.

Design/methodology/approach

Applying institutional theory as the underlying framework, this study examines an IAF’s ability to demonstrate legitimacy, which will shed light to the functions long-term survival. Using a unique data set from the NZ setting, which combines information obtained from “The Institute of Internal Auditors of New Zealand” with empirical firm data collected from publicly available sources, multivariate analysis is performed to test the prediction that IAF use is associated with earnings quality, measured using discretionary accruals, and external audit fees.

Findings

There is strong positive association between IAF use and external audit fees, which supports the complementary controls view, where better internal controls increase audit fees by increasing the demand for scope of external audit work. The authors find no significant relationship between IAF use and earnings quality, which is not entirely surprising.

Research limitations/implications

The aim is to empirically test the IAF value proposition and to delve deeper into the black box of IAF value drivers. Given the size of the NZ economy and limitations of data availability, total sample size used in this study is relatively modest. However, the analysis does yield significant results. Apart from academic contribution to knowledge, this study offers a profound list of practical contributions. Practitioners will be interested to learn about the IAF value proposition from an empirical viewpoint. Senior management (SM) will obtain value from the outcomes when contemplating IAF investment and sourcing decisions. Regulators will be inherently interested in whether IAFs should be mandated.

Originality/value

The aim is to empirically test IAF value proposition and to delve deeper into the black box of IAF value drivers. To the best of the authors’ knowledge, this is the first NZ-based academic investigation which examines the relationship between IAF use and earnings quality. Apart from academic contribution to knowledge, this study offers a profound list of practical contributions. Practitioners will be interested to learn about the IAF value proposition from an empirical viewpoint. SM will obtain value from the outcomes when contemplating IAF investment and sourcing decisions. Regulators will be inherently interested in whether IAFs should be mandated.

Abstract

Purpose

The purpose of this study is to examine which factors explain the use of an in-house internal audit function (IAF) in a voluntary setting.

Design/methodology/approach

Based on the foundations of agency and resource-based theory, this study examines a unique data set from the New Zealand setting, which combines information obtained from The Institute of Internal Auditors of New Zealand with empirical firm data collected from publicly available sources. Multivariate analysis is performed to test the prediction that in-house IAF use is associated with factors such as strong corporate governance, firm size, risk, complexity and firm ownership structure.

Findings

There is strong evidence that larger organisations are more likely to use an in-house IAF. The authors also find that listed firms and organisations that use a Big Four auditor are less likely to use in-house-based IAF. The authors learn that the IAF investment decision is dominantly influenced by a firm’s ability to fund an in-house IAF as compared to the IAF being used as a resource to improve firm performance to achieve sustained competitive advantage. This implies that IAFs need to ensure cost efficiency and eliminate unnecessary overheads and demonstrate and make visible the benefits the function offers to the host organisation.

Originality/value

The unique New Zealand setting, where the establishment and use of an IAF are voluntary, provides an environment to study factors that promote demand for internal audit services. Research implications are applicable to most parts of the world, including the UK, EU nations and the Asia-Pacific region, where IAF use is voluntary.
