ECR membership is a new category of RSNZ membership. In addition to the benefits of all individual members, ECR members will also belong to the RSNZ ECR Forum, a section of the Royal Society dedicated to engaging ECRs across all disciplines and fostering a collaborative, communicative, and respected community. ECR members can participate in all ECR events that RSNZ runs throughout the country. These events are targeted to the needs of ECRs, including communication, mentoring, networking skills, and career building. There will also be an emphasis on fostering relations between ECRs and Constituent Organisations, such as The New Zealand Historical Association (NZHA).
