Nin leads, and regularly presents at, an industry Risk & Regulatory forum created for leading individuals from a cross section of the finance sector to share information from a commercial and legal perspective, praised by one client as being "one of the most useful and progressive initiatives in the industry". Nin regularly speaks at local conferences, and writes, on regulatory matters.
