Speaking at the first Cabinet retreat of the eighth administration, Nandi-Ndaitwah said corruption weakens public trust and diverts resources from national priorities.
She urged ministers, regional governors and senior civil servants to demonstrate high standards of conduct in all government decisions, saying that ethical leadership is "non-negotiable" for those serving in public office, Xinhua reported.
Strengthening ethical governance forms part of wider measures to improve service delivery and ensure policies translate into tangible outcomes for citizens, said Nandi-Ndaitwah.
The president also emphasized the importance of national unity and social cohesion, saying strong institutions and stable governance remain central to Namibia's long-term progress.
The two-day retreat brings together Cabinet members, governors and senior officials to review the administration's priorities and prepare for the 2026 policy cycle.
