No - any communication that invites or induces engagement in an investment activity is a financial promotion and requires authorisation or s21 approval.
What counts as a promotion
Social posts, ads, landing pages, webinars, podcasts, email sequences - if they promote investment activity (mortgages, pensions, investments, insurance) they are regulated.
Exceptions
Certified high-net-worth and sophisticated investor exemptions apply under FPO, but are narrow and carry strict record-keeping duties.
