“I was extremely fortunate to have worked alongside many fantastic characters who created the strong identity and unique culture at the province. People who did more than anyone else in transforming Munster Rugby from an amateur organisation into one of the best clubs in Europe. “So many things have changed beyond recognition from when I joined Munster in the early days of professional rugby in 1997. “It was an amazing adventure as we navigated a new era of pro rugby, led by Garrett Fitzgerald, and watched Munster grow at an incredible speed on and off the pitch. The memories of those special days will live with me forever and I will always be grateful for the part I got to play in it. “After a very enjoyable eight years coaching with Ireland and Ireland A, I was delighted to return in 2012 and work with Axel again having coached him when he played with Shannon, Munster and Ireland. “The past 13 years have flown by and, while we have had some incredible highs, there have been devastating losses at Munster in recent years. We have lost some special people who are always in our thoughts and, when I move on, they will be the ones I think of most. “While many things have changed, the foundations and values in place will ensure that what is special about this province will endure long into the future. “I have to give special thanks to my family who have been by my side throughout this journey, and to my wife Cathy, and daughters Laura and Maeve, thank you for your unconditional support and here’s to making weekend plans.” Head of Rugby Operations and Interim Head Coach Ian Costello said: “Niallo has been one of the most widely respected figures in Munster Rugby for the past 28 years. "Personally, it has been an absolute privilege to work closely with him for over a decade and I can’t thank him enough for the level of support he has given me and so many others that have been lucky enough to work with him at Munster. “I first worked with Niallo in 2010 when he was Team Manager of Munster A and again in 2011 when he was Forwards Coach and Manager of the team that won the British and Irish Cup. I was fortunate to work with Niall for the next five seasons in his capacity as Team Manager of the senior men’s side and, along with many others, forged a deep friendship and a level of respect for him that continues to this day. “He represents everything that is good about the club, his passion, his values, his incredibly loyalty, and he is the first person that people turn to when they need help. What differentiates Niall from others is the deep level of care he shows every day for the people he works with. He will be hugely missed when he departs at the end of the season."
