A spokesman for Wagner confirmed that the ongoing costs of the scheme would be met by passengers, not the Government.
Wagner has previously said she doesn't expect airport rage among those not entitled to the fast-track scheme, saying it would speed processing times for everyone.
Recovering the cost of the border scheme would come after January's introduction of a border clearance levy, designed to eventually cover the cost of clearing passengers through airports and cruise ship terminals.
People with a return ticket to or from New Zealand are now hit with a total charge of about $22, included in the price of their airfare.
Figures supplied to the Herald show in the first five months of the levy Customs and Ministry for Primary Industries jointly took in $27.72 million excluding GST - above the forecast income of $20.22 million.
The agencies said the increased levy take was from higher than expected passenger numbers.
