Ms Provost said those problems had already been addressed by improvements to MPI's approval system, including inspections of every extraction site and extra staff on the ground in Northland.
As for the definition of a finished product, however, Ms Provost said that was a matter for the courts to decide.
Ms Furrell said NEPS had been preparing its case on exactly that issue for several months, by chance lodging its application for an urgent judicial review just as Ms Provost released her findings.
A further hearing was held in the High Court at Auckland on Friday to settle matters around timeframes and disclosure of evidence.
Other examples cited in the group's application include three logs, one of which weighed 6 tonnes, which had been lightly carved so they could be exported as Maori carvings and temple poles.
NEPS also claims the Ministry of Culture and Heritage should treat swamp kauri as a protected New Zealand object, which would require export approval under the Protected Objects Act 1975.
Ms Furrell said the group was lucky to have lawyers willing to work pro bono (without charge). A spokesman said MPI could not comment while the case was before the courts.
MPI guidelines state that a finished product "must be manufactured into its final shape and form and is ready to be installed or used for its intended purpose without the need for any further machining or other modification". Finished products could be a complete item or a component of an item but did not include dressed or rough-sawn timber, mouldings, panelling, furniture blanks or similar items.
