"It's time because we need to have family values back into Parliament and back into making policy," deputy leader Elliot Ikilei told the Herald.
"We're not targeting [Ross] but his actions have allowed for an opportunity," he said.
Ikilei said the event was being held at the Howick Bowling Club in the Pakuranga electorate for logistical reasons.
Ikilei, who recently accompanied former National leader and Hobson's Pledge spokesman Don Brash on his visit to Waitangi last week, wouldn't confirm whether Brash would be at Friday's meeting.
But he went on to say Brash's presence at the meeting would not be a distraction.
"The main reason why is that most of us have a shared goal of protecting our families, protecting our democracy."
Ikilei said Brash was not formally involved with the New Conservative Party but the pair were good friends.
New Conservative leader Leighton Baker said it was obvious there was going to be a good contest in Botany at the 2020 election.
"We're just positioning ourselves to have a good crack at it," Baker said.
Ross told the Herald he was aware of the meeting but wouldn't be attending.
"Political parties are entitled to have meetings, that's no problem, but I am listening to the Botany electorate and I am fronting up on people's doorsteps and out in the community, and I am appreciating the feedback," he said.
"There's been a range of feedback but there's been a huge amount of kindness and compassion and willingness to listen, and willingness to accept that I'm there to work on their behalf now going forward into the future."
Ross asked his first question of the year in Parliament today, a supplementary to Transport Minister Phil Twyford on whether he was still committed to a transport link from Auckland's airport to Botany.
Twyford said work was under way to look at extending a rapid transit service that would connect the airport with Puhinui, Manukau, Flatbush and Botany.
"My hope is that that will be something we'll be able to get up and running and make progress on in the coming years," Twyford said.
He said he would welcome Ross's co-operation as the local MP to progress the transport link.
