"To come away from a day like that, they know what WPC rugby is all about now," he said.
"They have certainly got some good learnings out of that and there were some good individual performances as well. And as a team they stuck in there until the end, which was really good."
He said what really cost them on Saturday was losing the battle in the forwards and missing tackles.
"[Otago] dominated in the forwards right from the start," Pere said.
"It was hard to get any system going because we were not getting any good ball, so we were on the back foot most of the day. It was a hard day at the office."
He said he was confident they would learn and improve throughout the year.
The Women's Provincial Championship runs for nine weeks before a grand final between the top two sides on October 25.
Bay of Plenty will travel to Christchurch for their next match against Canterbury this weekend. The Bay women's team will be back in Rotorua on September 13 to face Auckland.
Former All Black Hika Reid is the assistant coach of the Bay team.
Bay of Plenty 5 (Ashleigh Nathan try) lost to Otago 38 (Angie Sisifa 4, Greer Muir, Georgia Williams, Victoria Subritzky-Nafatali tries; Megan Manson pen).
