John Bracewell will step down as head coach of Ireland and return to New Zealand when his contract expires in December.
A former New Zealand offspinner and coach of the Black Caps for five years, Bracewell won't extend an Irish stint, which began after the 2015 World Cup.
The ICC's decision to promote Ireland to full test status earlier this year has played a part in the 59-year-old's decision to pull up stumps.
"Having been down the full-on full member road before with New Zealand Cricket, it is not my desire to do so again," Bracewell said.
"Whilst my wife and I have immersed ourselves into Ireland and Irish culture, we feel it is now time to return home to New Zealand and our families. I have therefore agreed with Cricket Ireland to finish up at the conclusion of my contract."
