"It's novel. It's actually never been imported into the country in this way before. Overseas, yes, but not here."
Despite the methods, he described the trio as "pretty simple people from a village in Spain".
The current street value in New Zealand for a gram of cocaine is between $250 and $400.
In overseas cases, clothing has been soaked in water filled with cocaine powder to make the drug stick to them, but Webby did not know how the Spanish dissolved their cocaine.
A drug dog detected cocaine in their luggage after they arrived in Auckland on LAN Airlines flight 801 from Santiago, Chile.
They were waiting to board a flight to New Caledonia.
Webby and the trio's defence counsel, David Niven, later agreed on an estimated weight of the cocaine because it would be expensive to extract, Webby said.
Both Webby and Niven confirmed Guerrero-Nieto had given birth while in custody.
Niven said he did not know the baby's gender or if it was in Guerrero-Nieto's care behind bars.
He would not say who the baby's father was. The Herald on Sunday has seen Guerrero-Nieto holding hands with Beltran-Velez while in the dock.
A Corrections Department spokeswoman would not say if Guerrero-Nieto's baby was in her care. Children may remain in the care of their jailed mothers in self-contained units at the country's three womens' prisons until the child is 2, the spokeswoman said.
Four children are currently living with their mothers, she said.
Webby said Guerrero-Nieto, Beltran-Velez and Casal-Carmona could be jailed for up to 20 years.
Department of Internal Affairs spokesman Michael Mead said the baby will not be a citizen unless one parent is a New Zealand citizen or permanent resident.
An application for citizenship can be made after the child has lived here for five years. The Immigration Minister could also use discretion to grant citizenship in special circumstances, Mead said.
Immigration spokesman Marc Piercy said the department "wouldn't deport a child without its parents".
