We Are Finished Taking Bookings for Workplace Flu Vaccinations
We have now finished taking bookings for our 2026 workplace flu vaccination season. Each year, there comes a point when onsite clinic availability closes and we shift our full focus to completing the remaining booked visits.
Why workplace flu vaccination timing matters
Workplace flu vaccination works best when it is planned early. In New Zealand, the flu vaccine is available from 1 April each year, before winter starts. Health New Zealand recommends annual flu vaccination for everyone over 6 months of age. Healthify also notes that it takes about two weeks for the flu vaccine to become most effective. That is why many employers aim to organise vaccination before winter pressure builds across their teams.
Flu season in Aotearoa New Zealand usually runs from May to October. During this period, workplaces often see more staff illness, more disruption, and more pressure on rosters and day to day operations. Influenza spreads quickly through shared environments, including offices, warehouses, customer facing workplaces, staff rooms, and meeting spaces.
Why we stop taking bookings before the season ends
The wider influenza immunisation programme continues well beyond early winter. Healthify states that the influenza immunisation programme runs from 1 April to 31 December. Even so, an onsite workplace vaccination service has its own operational limits. There comes a point in the season when remaining clinic time needs closing as winter influenza viruses are circulating in the community and vaccination is of less benefit.
Closing bookings before the very end of the winter vaccination period helps us deliver the remaining clinics properly and safely.
Why employers still prioritise flu vaccination
Many employers offer flu vaccination to their staff because it is a simple way to support worker health through winter. The Immunisation Advisory Centre says annual influenza immunisation is recommended for everyone who can be vaccinated, and it notes that many employers offer the vaccine to staff. This fits with what we see each year. Businesses want to reduce barriers, make vaccination easier to access, and help their people prepare before flu spreads more widely.
The flu vaccine is updated each year to match the strains most likely to circulate in New Zealand. Healthify explains that you need a flu vaccine every year because the vaccine is made to match the strains likely to be in Aotearoa New Zealand, and because protection becomes less over time.
What this means for businesses now
For businesses that already have a booking with us, your clinic will continue as planned. We will keep working through our remaining workplace visits as we finish the season.
For businesses that missed out this year, the best next step is to plan earlier for 2027. The most useful workplace flu vaccination programmes are usually the ones organised well before winter demand becomes compressed. Early planning gives more choice around timing, better internal communication with staff, and a better chance of vaccinating people before winter flu exposure rises. Email Onsite Health at mail@onsitehealth.co.nz and we will add you to our database to contact early next year.
This matters because winter is when people are most likely to come into contact with influenza, and the vaccine needs time to work. Booking early helps line up workplace access with the period when vaccination is most useful.
Looking ahead to next season
Flu vaccination remains one of the most practical seasonal health steps a workplace can support. It helps protect staff, supports business continuity, and reduces some of the pressure that winter illness can place on teams. While we are no longer taking new bookings for our 2026 workplace flu vaccinations, the value of planning ahead remains clear.
If your business missed the booking window this year, now is a good time to note it for next season. Early action gives the best chance of securing a workplace flu vaccination clinic during the most useful part of the winter vaccination period and after flu vaccines become available at the start of April each year.
