For those wanting the extra challenge of competitions and exams, there are plenty of options!
There are competitions each year in the Hutt, Porirua, and Wellington. These are a great opportunity to listen to other performers of a similar level and receive feedback from an adjudicator.
For those who are wanting to do exams, I suggest NZMEB: https://nzmeb.org/ This is the only examination board through which students can gain NCEA credits. I am happy to put students through exams with Trinity or Royal exams also.
I take most of the students through Trinity theory books regardless of whether or not they sit the exams.
