He asked Weta Digital to restore and colourise every photographic image used in the exhibit.
"It's amazing how it makes a century of history melt away, and you suddenly see people that are no different to your own friends and workmates today," said Sir Peter.
"This is an exhibition for all New Zealanders, and I'm excited to continue expanding it to tell New Zealand's story as it happened, 100 years earlier."
The evening with Sir Peter will be held on Thursday, June 2, at the ANZ Viaduct Events Centre in Auckland.
Tables and tickets for the event, which includes a three-course meal with New Zealand wine and beverages, costs $5000 for 10 guests, or $500 for individual tickets.
