In early April 2026, Humphrey Wattanga was nominated as Kenya’s High Commissioner to South Africa, marking his transition into diplomatic service pending parliamentary approval. The nomination followed his exit as Commissioner General of the Kenya Revenue Authority (KRA), where his tenure concluded after his contract was not renewed, with Dr Lilian Nyawanda stepping in on an acting basis. This shift reflects a broader foreign service reshuffle announced around April 8–9, 2026, signalling confidence in his institutional and fiscal expertise.  

Before this diplomatic elevation, Wattanga spent over two decades in corporate finance, taxation, and revenue administration, building a reputation within Kenya’s public finance architecture. His leadership at KRA placed him at the centre of tax policy implementation, compliance enforcement, and revenue mobilisation, aligning fiscal systems with national development priorities.  

His professional grounding lies in finance and accounting, with extensive experience in managing complex financial systems and regulatory environments. This technical foundation informed his approach to public-sector leadership, particularly in enhancing efficiency and accountability within revenue-collection frameworks.  

From these foundations, Wattanga’s career now arcs into diplomacy, where his background in fiscal governance and institutional management is expected to inform Kenya’s economic and bilateral engagement with South Africa.
