The seminars were at Otago Girls High School, Kaikorai Valley College, Otago Boys High School, Columba College, Bayfield High School, Queens High School and Logan Park High School, and drew more than 450 teachers from around the region.
They were some of the 14,000 nationwide who would take part in support days between now and the end of August.
The seminars, jointly organised by the Post Primary Teachers Association and the New Zealand Secondary Principals Council, allowed subject specialist teachers to work with colleagues from a range of schools to develop each area of the new curriculum.
PPTA president Kate Gainsford said the days were designed to help teachers align their subjects with a curriculum that was a radical departure from what had gone before.
"They're a great opportunity for teachers to benefit students by working together - something that rarely happens on such a broad scale.
"These days are about the profession taking care of professional matters."
While the changes in the curriculum could be seen as largely positive, teachers and schools needed time and resources to make it work.
The seminar days were a hands-on way of getting this process started, she said.
The new curriculum will be implemented progressively until February 2010 when it will become mandatory and replace current curriculum documents.
