Key Responsibilities of External Audit Firms

1. Financial Statement Verification

External auditors review balance sheets, income statements, cash flow statements, and accompanying notes to ensure they comply with New Zealand Generally Accepted Accounting Practice (NZ GAAP) or International Financial Reporting Standards (IFRS).

2. Internal Controls Assessment

Auditors evaluate the design and effectiveness of internal financial controls to assess whether financial information is recorded and processed accurately.

3. Compliance Checks

External audit firms confirm whether the organization complies with applicable legislation, tax obligations, and financial reporting standards.

4. Fraud Detection

Although not their primary goal, external auditors may identify signs of fraud or financial misrepresentation through their rigorous procedures.

5. Risk Management Insights

Their findings often reveal financial risks or vulnerabilities, which can inform better governance and operational controls.

The External Audit Process Explained

Understanding how external audits are conducted helps businesses prepare better and streamline the process. The typical audit follows several technical steps:

Step 1: Engagement and Planning

An engagement letter is signed, defining the scope, timeline, and responsibilities. The audit team gathers initial information about the company, including financial statements, policies, and prior audit reports.

Step 2: Risk Assessment

Auditors identify key risk areas where material misstatements may occur. This may include revenue recognition, asset valuations, or complex transactions.

Step 3: Internal Controls Testing

This involves evaluating processes such as invoicing, payroll, procurement, and reconciliations to determine their reliability.

Step 4: Substantive Testing

Auditors perform detailed procedures, such as sampling transactions, verifying account balances, and cross-checking financial data with third-party sources.

Step 5: Evaluation and Reporting

Findings are compiled into a formal audit report. If financial statements are accurate and compliant, an unqualified (clean) audit opinion is issued. Any concerns or limitations are documented in modified opinions.

Why External Audits Matter

1. Enhances Transparency and Trust

Audited financials build credibility with investors, lenders, regulators, and customers. They show that a business is committed to accurate reporting and ethical practices.

2. Mandatory Compliance

In New Zealand, certain entities—such as public companies, large overseas-owned businesses, and charities over a specific threshold—must undergo external audits as per the Financial Reporting Act 2013.

3. Facilitates Business Growth

Clear and accurate financials attract investors, support loan applications, and assist in merger or acquisition discussions.

4. Identifies Operational Improvements

Audit recommendations can improve efficiency, reduce errors, and enhance risk management.

5. Encourages Good Governance

External audits reinforce strong governance by holding leadership accountable for financial accuracy.
