why a corporate finance is required when internal and external auditor are reliable

Auditors are used to keep track of various transactions and accounting activities of the company. They are not qualified enough to advise companies on IPO, raising finances, mergers, acquisitions etc.

For that you need investment bankers and corporate finance advisors.

Auditors are only concerned with the accounting issues. However bankers and corporate finance advisors need to know accounting along with other strategic and operational issues.
