Millennium 2000 New Zealand Mint limited gold coin 1/30 oz (99.99) pure gold

Can anyone identify more about this? https://www.grays.com/lot/8436-5061593/memorabilia/millennium-2000-new-zealand-mint-limited-gold-coin-99-99-pure-gold?srsltid=AfmBOor3mo6XGEJW17KcUmP6nn_ScaONSxZD-5b2UIPjRyBIP2UUkv7z

I have one but can't seem to find any information about it online and am not sure how to add it to my Nimista collection. 

Thank you!
