We’re extremely proud of our history and heritage as a firm of trustworthy business advisors and chartered accountants. Mark Gwilliam came to New Zealand, from the UK in 2001. After brief spells with two well-known global accounting firms, he formed Business Advisory Services. His focus was (and continues to be) to set the tone for the firm’s core values, ethics and culture.
From humble beginnings, the firm has grown from strength to strength. It has matured from being a small accounting and tax services practice to one that helps small business owners, entrepreneurs and executives navigate complex challenges including strategy, risk management and internal audit, managing shared-service centres and operations.
We’re a firm of Chartered Certified Accountants, Chartered Accountants and Business Advisors based in Auckland with clients in New Zealand and overseas. We are determined to remain highly professional and approachable. We’re big enough to cover most clients’ needs but remain the right size to guarantee we still provide personal attention. With Business Advisory Services, you’re in safe hands. We have a team with proven skills and experience, and the innovation to help you make good financial decisions to create success, value and prosperity.
We are determined “To be an international professional services company that helps our clients and people succeed in their busy working and personal lives”.
Our mission is “to deliver consistent and excellent service to our clients; to offer rewarding careers & professional fulfilment for our teams; and to attain financial success so we can grow and prosper”.
We take our “vows” very seriously and set ourselves very high standards. In carrying out our obligations to you, work will be delegated to staff with the appropriate levels of skill and knowledge. This enables us to remain efficient, without compromising our quality to you. However, I accept full responsibility for my team and I will remain the primary contact for you.
