The seventh charge relates to an allegation that Tahir had the live plant hoya latifolia in her possession on February 8 this year.
Each of these charges laid by the Ministry of Primary Industries (MPI) attracts a maximum penalty of five years' in prison.
The Ministry alleges the offences were committed between June 2018 and April 30 this year.
Tahir was remanded until January 6 when she is expected to enter pleas to the charges.
Outside court, Ministry of Primary Industries senior prosecutor Morgan Dunn confirmed to the Bay of Plenty Times the allegations centred around Tahir's attempts to import banned plant materials sourced from Hong Kong, Taiwan, Thailand and Singapore.
Dunn said while the matter was still before the courts he would not comment further.
