Mosgiel-based Mr Sapsford (60), a former All Black, owned the purpose-built 1930s Art Deco dental surgery and worked there each Friday.
His death after a jet-boating accident put an end to dental care in the Maniototo, forcing clients to travel to the next closest practices, in Palmerston and Alexandra - or go without.
Mr Sapsford's daughter, Amie Pont, and his two former dental assistants, Sylvia Carson and Carolyn Steele, have arranged for a locum dentist to service Maniototo clients on four days in May, although the surgery's long-term future remains uncertain.
The land, building and surgery equipment is for sale.
Mrs Pont - Project Maniototo co-ordinator - said she hoped the building would continue to be used as a dental practice.
She said bookings for the May dates had been steady, although all past, present and potential clients were asked to register their interest in continued dental care at Ranfurly to establish the level of demand.
It was hoped a dentist or group of locums would be interested in buying, or practising at, the Ranfurly centre if satisfied of the need from residents throughout the wider area.
• Dunedin dentist Selwyn Chalmers will work out of the Ranfurly practice on May 5, 6, 10 and 11.
