Physiotherapist Brett Harrop is moving on after five summers with the team.
He has secured a two-year contract with Sri Lanka Cricket and will work with the national team.
Harrop signed with the Volts in 2016. But it was a seasonal contract and he would travel overseas for work during the off-season.
But Covid-19 put up a road block.
“I love everything about Otago Cricket and the Otago Volts," Harrop said.
"However, with Covid-19, and the part year nature of my contract, it made it too difficult to secure contract work that was normally available to me through the off season.
"The opportunity to stay involved in cricket and with a national body is very exciting.
“Although I will be based mostly overseas over for the next two years, my home is Dunedin.
"My family will remain here and I will come back as often as possible."
Harrop’s wife, Gwen, is the general manager of the Dunedin Gymnastics Academy. The couple have two children, Luka (9) and Amelie (7).
Harrop will leave for Sri Lanka at the end of this month.
Otago Cricket Association (OCA) performance manager Simon Forde said Harrop had done a "fantastic" job.
"He’s a quality physio, well respected and has brought plenty of cricket nous to our playing and management group," Forde said.
"We wish him all the very best but will certainly miss him."
Harrop is the third departure from the Volts management team in the last few months.
Head coach Rob Walter has transferred to Central Districts and will coach the Stags next season. Assistant coach Adam Miles has moved to Southland to support his wife in the family business.
Strength and conditioning coach Blaine Clancy has also resigned. He will leave his post in August.
That leaves Forde as the only remaining member of the Volts’ management structure.
It is a lot of change, but OCA chief executive Mike Coggan was confident of stitching together a good management team for next season.
The Volts used two physiotherapists this year. Scott Wilson joined the team and would seem a likely replacement, although the position is a New Zealand Cricket appointment.
Applications for the head coaching role close today.
"You always get one or two who apply at the very last minute but we’ve got 11 or 12 applications of varying quality," Coggan said.
"We are in a situation where we will be able to shortlist some quality candidates."
The interview panel will include Coggan, Forde and a representative from New Zealand Cricket and the New Zealand Cricket Players Association.
All going well the interview process could get under way next week.
"There are applicants from overseas as well, which complicates things with Covid and all that.
"We’ve probably got less applicants from within the country than we would like."
Coggan said is was unfortunate to have so many key personnel leaving at one time.
"It is not because of anything happening within the environment. It has just been the perfect storm of individuals leaving for their own reasons."
