"Not many doctors - especially younger ones - are willing to commit to the business or administration side of a solo practice. She is an extremely proficient general practitioner with vast experience."
Dr Coetzee began her career in 1986 in Pretoria, working at a military hospital and in solo practice.
"In 2007 I moved to Ireland where I did locum and after-hours work," she said.
"For nearly five years I have built up a client base at the Gonville Health Centre, but I'm happy now to move into solo practice."
She will run her practice across the road at 197 Wicksteed St and, in fact, already has her sign out on display.
Dr Moore had a client base of just under 1000, quite a few less that many other general practitioners in Whanganui.
He will keep himself busy "pottering around" his two farm blocks in Upokongaro, north of the city, in his retirement.
He runs sheep, cattle, pigs, Muscovy ducks, a donkey and his passion, thoroughbred horses on his two blocks on SH4.
"In the short term I will continue my work at the sexual health clinic, defence force medicals and Work and Income," Dr Moore said.
