Mid Central District Health Board is bringing a new mobile "pop-up" vaccination unit to workplaces or community groups in the region, including Tararua.
Employers and community leaders were being encouraged to register interest for the new mobile vaccination unit.
Pop-up clinics had already proved popular with employers.
Covid-19 Vaccination Programme senior responsible officer Deborah Davies said the van would support an increase in pop-up vaccination sites.
"In the event of a Covid outbreak, the impact on workplaces can be quite substantial, with long absences and the potential for the virus to spread between staff members," Davies said.
