A high-level meeting between New Zealand and the UN nuclear watchdog took place on Monday, after a controversial go-ahead for dumping treated nuclear radioactive water into the Pacific.

After a two-year review, the International Atomic Energy Agency have given it the green light - stating the release - over 30 to 40 years - will have a negligible impact on the environment.

The water was tainted during the 2011 Fukushima nuclear disaster.

Foreign Minister Nanaia Mahuta sat down with International Atomic Agency Director General, Rafael Grossi, but the meeting was closed to the media.

Senior lecturer at Auckland University, Dr David Krofcheck, joined Kerre Woodham to discuss.
