Two people have been convicted on seven charges laid over a $1.6 million advertising scam.

Noelene Banton and Johannes Middledorp sold advertising to magazines that either didn't exist or had tiny circulations.

Both have been granted bail and will be back in the High Court in Wellington for sentencing next month.

Two others have previously been sentenced for their involvement, while Anthony Hendon, the man accused of being the ringleader, is due to be sentenced tomorrow.
