Abstract—The primary research question considered in this
paper is whether auditor tenure has any effect on audit quality.
This study is motivated by the newly introduced legislation in
South Africa regarding mandatory audit firm rotation, which is
premised on the belief that lengthy auditor tenure decreases
audit quality. Using data from 1 273 auditees listed on South
Africa's JSE Limited for the years 2010 to 2020, statistical
analysis of the findings revealed that auditor tenure is positively
associated with audit quality during the early years of the audit
engagement because of a learning effect and auditor tenure is
negatively associated with audit quality in the later years of the
audit engagement because of an independence threat. Statistical
analysis of the data revealed that through a learning effect audit
quality increases until the 13th year of the auditee auditor
relationship where due to an independence threat audit quality
begins to decline.
Index Terms—Auditor quality, rotation, tenure, quadratic
equation.
