Mikaere joins fellow Rotorua player Samantha Sinclair in the team.
In a shock selection former New Zealand captain Katrina Rore (nee Grant) has been dropped for the series.
"It was a tough call, it happened to be that others could do it better, she's not included but everybody will be available for World Cup," Taurua said.
"She's totally disappointed but I know she will be back."
The latest selection proved one of Taurua's toughest yet during her short reign as head coach, as she put 25 hopefuls through a rigorous training camp in Auckland this week.
"They have been put under the pump physically, mentally and emotionally," she said.
"We needed to set the standard with what's required within the team – I've been inspired by the intent and focus out on court."
Taurua said with the step up in intensity, her job of selecting had become more difficult particularly through the mid-court and defensive ends which hold plenty of promise.
"I'm liking what I'm seeing," she said.
