Register for one of eHaus Waikato's Open Construction Days here.
The 2014 International Passivhaus Conference was held in Aachen, Germany this year. New Zealand was represented there with two of our leading professionals presenting. Dr Paola Leardini of The University of Auckland presented a paper on "How do Passive Houses perform in New Zealand" and Dr Kara Rosemeier, who is a Director of the Passive House Academy, a poster session on "Healthy and affordable housing in New Zealand: the role of ventilation."
HERE is summary of the conference which if you are interested in Passive House is a very good read.
