The Nelson-based carrier will take over the route from Sounds Air, which announced in July it will no longer fly from Blenheim to Christchurch or Christchurch to Wānaka from the end this month.
Originair will fly twice a day from Tuesday to Thursday, and once on Monday, Friday and Sunday.
It will use its fleet of 18-seater, pressurised twin turboprop British Aerospace Jetstream planes, crewed by two pilots.
If the flights are a success, the airline will look to boost the route to two flights every day.

"This swift transition ensures ongoing connectivity for travellers and communities across the South Island.
"Originair’s entry into the route reinforces a shared commitment to maintaining strong regional access.
"The announcement will be welcomed by many, as the route supports not only business and leisure travel, but also plays a crucial role in enabling patients to access specialist care at Christchurch Hospital.
"Enabling regional routes are vital to Christchurch’s role as the South Island hub, connecting communities and supporting economic activity across the region.
"We’re looking forward to seeing the white and yellow Jetstreams become a regular feature of our whanau."

"A consistent return service to Christchurch is important for our business community, accessing health care, and as a key market for tourism.
"We’re pleased to see Originair’s plans to scale up this route as passenger demand is established."
