Thailand has a large number of accounting and legal firms that can assist with due diligence.
These range from the leading international audit, tax and advisory specialists to mid sized foreign and local firms, to independent business consultants and legal professionals who have lived in Thailand for some time.
The larger international firms are staffed by both foreign partners and locally engaged Thais and provide the full range of services available by the same international companies in New Zealand.
The New Zealand Thai Chamber of Commerce directory contains contact details of some business consultants who are members of the Chamber.
