Domigan, who has prepared some wonderful surfaces at the venue since 2005, has accepted a role at Christ's College to manage the school's fields.
Before moving to Queenstown, the 58-year-old built his reputation by turning out some belters at Alexandra's Molyneux Park.
All his hard toil was recognised by New Zealand Cricket in 2011 when he was presented with a distinguished services award for cricket turf management.
Domigan could not be reached for comment but Dykes said his absence would be a huge loss.
''He is an outstanding turf man and has proved his worth wherever he has been,'' Dykes said.
''He will be a hard man to replace but the ground is established. He has just built up so much experience over the years.
''He just has such a great sense with timing in terms of rolling, watering and covering. Everybody loves going to Queenstown because they know they are going to get a good pitch.''
Queenstown Lakes District Council parks manager Mike Weaver, himself a former first-class groundsman, has been enlisted to help find a replacement. Applications for the role close at the end of the week.
''It will be nearly next week before we get our first opportunity [to review the applications] and, depending on who we get applying, have to go through an independent interview process which could take up to two or three weeks,'' Weaver said.
''And then who knows as to their availability. Hopefully, they will be available fairly soon.''
It could be as late as early November before there are some new boots on the ground.
