About Audit Commission

Audit Commission

The Audit Commission is the Hong Kong Special Administrative Region's independent public audit body, headed by the Director of Audit. It is one of Hong Kong's oldest government institutions: the first Auditor General, Adolphus Edward Shelley, was appointed in 1844, only three years after the colony's founding. Known as the Audit Department before the handover, it was renamed the Audit Commission on 1 July 1997. Under Article 58 of the Basic Law it functions independently and is accountable to the Chief Executive. It conducts regularity audits certifying the government's accounts and value-for-money audits of departments and public bodies, submitting three reports a year to the President of the Legislative Council. Its official website is aud.gov.hk.

The Commission's stated purpose is to provide independent, professional and quality audit services to the Legislative Council and public sector organisations, in order to help the government enhance public sector performance and accountability in Hong Kong. The Audit Ordinance (Cap. 122), enacted in December 1971 and revamped in August 2025, governs the appointment, tenure and powers of the Director of Audit, who has wide rights of access to the records of departments. The 25th holder of the office in its long line, Nelson Lam Chi-yuen, took office as Director of Audit in July 2022.

Origins: audit in Hong Kong since 1844

Public audit in Hong Kong is nearly as old as the colony itself. Adolphus Edward Shelley, the first Auditor General, was appointed in 1844, in the first years of British administration, to bring order to the public accounts of a new colonial government. He was followed by a succession of colonial audit officers — William Caine, who combined audit with other senior offices in the early administration, William Thomas Mercer, William Hepburn Rennie and their successors through the nineteenth century — as the office's title evolved from Auditor General to Auditor and eventually to Director of Audit in the twentieth century.

Through the colonial period the audit office performed the classic function of a colonial audit department: checking the regularity of government transactions, certifying accounts, and answering through the Governor to London's colonial audit machinery as much as to local scrutiny. The modern institution, however, is a product of the 1970s, when Hong Kong's public finances grew enormously in scale and the Legislative Council's role in scrutinising expenditure expanded, creating the need for a statutory local audit regime with published reports and a parliamentary public accounts committee to examine them.

The Audit Ordinance and the modern regime

The Audit Ordinance (Cap. 122) was enacted in December 1971 and laid down the modern framework: the appointment and tenure of the Director of Audit, his duty to audit the accounts of the government, his statutory authority to conduct regularity audits, and his right to report to the legislature. Under the ordinance the Director has wide powers of access to the records of departments in the performance of his duties — the essential legal guarantee without which public audit cannot function, since an auditor dependent on the audited for information is no auditor at all.

The ordinance has been periodically updated, most recently in a revamp that took effect in August 2025 modernising the appointment, tenure and powers provisions. Across these changes the constitutional essentials have remained stable: the Director is appointed by the head of government — the Governor before 1997, the Chief Executive since, with SAR-era directors appointed by the central government on the Chief Executive's nomination — holds security of tenure under the ordinance, reports publicly, and is subject to no direction as to what to audit or what to find.

Independence under the Basic Law

The handover settlement preserved and constitutionalised the institution. Article 58 of the Basic Law provides that a Commission of Audit shall be established in the Hong Kong Special Administrative Region, that it shall function independently, and that it shall be accountable to the Chief Executive. On 1 July 1997 the Audit Department accordingly became the Audit Commission, and Dominic Chan Yin-tat, who had become Director of Audit in 1995, continued as the first Director of Audit of the SAR, serving until 2003.

Independence in this model has a specific meaning. The Director reports to the Chief Executive, not to the Legislative Council and not to the Financial Secretary whose accounts he audits; but his reports are laid before the Legislative Council and examined in public by its Public Accounts Committee, so that accountability runs through publication and legislative scrutiny. The Commission describes its own position as operating independently from the rest of the government — like an external auditor of the government's accounts, with some functions resembling an internal auditor's, but with government departments and the public sector as its audit subjects.

Regularity audit: certifying the accounts

The first of the Commission's two audit types is regularity audit. Its purpose is to provide overall assurance of the general accuracy and propriety of the financial and accounting transactions of the government and other audited bodies — in essence, to certify that the accounts are properly kept, that expenditure was incurred for authorised purposes, and that the financial statements present a true position. The Audit Ordinance gives the Director statutory authority for this work, and it culminates each year in his report on the Accounts of the Government of the Hong Kong Special Administrative Region, submitted to the President of the Legislative Council in October.

The audit universe extends well beyond the general government accounts. The Director also audits the Exchange Fund — the monetary reserve managed by the Hong Kong Monetary Authority — the Hong Kong Housing Authority, five trading funds, and more than sixty statutory and non-statutory funds and other public bodies. This breadth makes the Commission the auditor of substantially the whole of Hong Kong's public balance sheet, and its certification work, though less publicly visible than its value-for-money reports, is the foundation of the territory's financial accountability.

Value-for-money audit: the three Es

The second audit type, and the one that makes news, is the value-for-money audit: an examination of the economy, efficiency and effectiveness — the "three Es" — with which a bureau, department, agency, public body or audited organisation has discharged its functions. Value-for-money audits are not primarily statutory: except where the Director has statutory authority over particular bodies, they are conducted under a set of guidelines agreed between the Director and the Public Accounts Committee and tabled in the Provisional Legislative Council by the Committee's chairman on 11 February 1998. The guidelines guarantee the Director great freedom in choosing subjects and presenting findings, define the audited organisations covered — including bodies receiving more than half their income from public money — and provide for two value-for-money reports to the Legislative Council each year.

The Director accordingly submits three reports a year in total: the accounts report in October and two value-for-money reports, in April and October. Recent value-for-money subjects have ranged across the whole of government — the Continuing Education Fund and the management of the Anderson Road development project are among the examples cited in professional accounts, alongside chapters on government support for charities, monitoring of charitable fundraising, management of squatter structures and district council funds in Report No. 68 of 2017. Each report's chapters are selected for hearings by the Public Accounts Committee, whose own reports and the government's responses complete the accountability cycle. Director Nelson Lam has likened the Commission's role to that of a "family doctor" performing body checks on departments and organisations — a metaphor for audit as diagnosis in the interest of the patient's health rather than prosecution.

The Public Accounts Committee cycle

The Commission's reports do not operate alone; they feed one of the Legislative Council's oldest scrutiny mechanisms, the Public Accounts Committee. The Director's reports are considered by the Committee in accordance with section 12 of the Audit Ordinance and Rule 72 of the Legislative Council's Rules of Procedure. The Committee selects chapters for public hearings, at which controlling officers of the departments concerned must answer for the findings; the Committee then reports its own conclusions, and the government responds with undertakings to remedy the deficiencies identified.

This cycle — independent audit, published report, public hearing, government response — is the practical machinery by which Audit Commission findings change administrative behaviour. Departments know that value-for-money findings will be examined in public and followed up, and the Commission tracks implementation of accepted recommendations. The arrangement copies, in Hong Kong form, the Westminster model linking an auditor-general to a parliamentary accounts committee, adapted to the SAR's Basic Law structure in which the auditor is accountable to the Chief Executive while reporting to the legislature.

Directors of Audit and professional standards

The line of office-holders runs unbroken from 1844. The published list records the colonial Auditors General, Auditors and Directors of Audit — including figures such as William Henry Marsh in the 1880s and the twentieth-century directors who served through the war years and the post-war expansion — down to Dominic Chan Yin-tat, the last colonial director and first SAR director (1995-2003 in the combined span). His SAR successors included David Sun, who signed Report No. 68 in 2017, and Professor Nelson Lam Chi-yuen, the 25th Director of Audit in the Commission's reckoning, who took office in July 2022 on the nomination of Chief Executive John Lee and appointment by the central government, bringing some thirty years of accounting and auditing experience to the post.

The Commission's work is governed by its own auditing standards, laid down as a framework for the proper conduct of audits by its staff; compliance with those standards is designed to ensure compliance in all material respects with the auditing standards of the International Organization of Supreme Audit Institutions and of the Hong Kong Institute of Certified Public Accountants. The Commission also engages with the wider public-sector audit community: in January 2024 it hosted the fifth Hong Kong Public Organisations Internal Audit Roundtable, bringing together internal audit executives from some thirty local public organisations to exchange practice on performance audit — the local counterpart of its value-for-money work.

The Commission today

Today the Audit Commission continues its dual programme from Hong Kong: regularity audits certifying the accounts of the government, the Exchange Fund, the Housing Authority, the trading funds and dozens of public funds and bodies; and two value-for-money reports a year examining how economically, efficiently and effectively public money has been used. Its full reports and summaries are published on aud.gov.hk, and its findings — examined by the Public Accounts Committee and answered by the government — remain a principal source of documented scrutiny of Hong Kong's administration. The revamped Audit Ordinance of August 2025 updated the statutory framework under which the Director works.

For a directory of Chinese public institutions, the Audit Commission is the entry with the longest pedigree: an audit office founded in 1844, statutorily framed by the Audit Ordinance of 1971, constitutionalised by Article 58 of the Basic Law, and renamed at the handover in 1997. Its three reports a year, its wide statutory access to public records, and its partnership with the Legislative Council's Public Accounts Committee make it the financial conscience of the Hong Kong government — an institution older than almost every department it audits.
