In February 2018, Nyagura was arrested by the Zimbabwe Anti-Corruption Commission (ZACC) and charged with recommending "the conferring of a doctor of philosophy degree to Grace Marufu Mugabe without the approval of the University Council and Senate Committee."

Nyagura began his career as a mathematics teacher and he then joined the Faculty of Education at UZ. In 1981, he became a member of the Faculty of Education's Committee of Inquiry on the Restructuring of the Faculty. During the same period, he was also appointed to be the chairman of a subcommittee within the Faculty of Education which focused on technology.
In 1982, Nyagura was then appointed to be Deputy Dean of the Faculty of Education after showing his capabilities to be able to lead. Since then, he began to head several departments aligned to curriculum development within the country.
In 2010, he was appointed to be the Chairman of the Zimbabwe Council for Higher Education Committee on Accreditation and Quality Assurance. In 2014, he was appointed to be the chairman of a ten-member board to oversee the Zimbabwe School Examinations Council (ZIMSEC). Nyagura has also published several articles on the education system in Zimbabwe.

- The Zimbabwe Institute of Management Harare Regional Public Services Manager of the Year (2012)
- The Zimbabwe Institute of Management Public Services Manager of the Year (2012)
He is regarded as one of the many who was awarded unfettered authority by Mugabe. Thus he was referred to as an advocate of the Mugabe led government whose main aim at the institution was to quell opposition. In 2009, students who were at the institution petitioned the European Union Chairman to treat Nyagura in a manner akin to what it was doing to the so-called 'Mugabe's disciples'.
