Gary Kirsten has resigned as Pakistan's limited-overs coach after six months in the role and Test coach Jason Gillespie will be in charge for the white-ball tour of Australia which starts next week.
The former South Africa batter was appointed on a two-year contract in April at the same time as Gillespie took over the Test side.
Kirsten is reported by ESPNCricinfo, external to have had a strained relationship with the Pakistan Cricket Board (PCB) about selection issues.
The 56-year-old has previously coached India - guiding them to a 50-over World Cup win in 2011 - and his native South Africa as well stints with various T20 franchises including in the Indian Premier League.
Pakistan face Australia in three one-day internationals - starting on 4 November in Melbourne - before three T20 internationals.
The PCB has put the former Australia bowler in charge for those white-ball matches following Pakistan's 2-1 Test series win against England.
