The national sprint cycling coach Justin Grace has resigned after five years in the role.
Grace says the lengthy time away from his family is no longer sustainable, having averaged 200 days away each year.
BikeNZ High Performance director Mark Elliott says Grace has been responsible for developing the sprint programme from scratch to its current high world ranking.
He says with a programme of sports science, strength and conditioning and coach support well established riders will be catered for in the immediate future.
