Agency vs Managing Your Own Temp Staff: What Does Relief Cover Really Cost?

Many centres keep their own list of casual relief teachers to save on agency fees. The hourly wage looks cheaper, but it isn't the full cost. You also pay holiday pay, KiwiSaver and ACC on top of wages, and your manager spends time finding cover, chasing replies and doing payroll. Recruiting, vetting and inducting new relievers adds more, as does every shift left unfilled.

How the agency vs in-house calculator works

Shifts filled × hours × hourly rate. For your own staff, it adds employer on-costs (holiday pay, KiwiSaver, ACC). With an agency, these are included in the rate.

Minutes spent finding cover and doing admin per shift × number of shifts × your manager’s hourly cost.

Advertising, interviewing, police vetting, safety checking and inducting your own relievers. With an agency, this is included

Each shift you can’t fill × what a gap costs you, such as overtime, a room closure or turning families away.
