There's concern about how many people drop out of apprenticeships, according to new reports.

Vocational Education Minister Penny Simmonds has told a conference more than half of trainees aren't completing training.

She says it's driven by a number of reasons, but she's pointing the finger at the previous Government incentivising training.

Simmonds says it means many signed up despite not being that interested - and didn't complete their apprenticeship.
