He described the Confederate flag as "one of the most potent symbols of slavery and oppression" and said the club's attachment to it was "appalling".
The Wellington man, who has both Indian and Caucasian ethnicity, emailed the club asking if members would take the petition into consideration at their AGM and if they would have "constructive dialogue" with him about it.
But todayclub secretary Sonja Hickey, who also oversees the teams and promotions, sent a response to Aulakh, who has forwarded it to NZME, saying members wouldn't require his help.
"We have a broad demographic of members and are culturally very diverse, a number of our executive are in fact Māori and we have an even number on the executive of both male and females."
She said some members were solicitors, policemen and policewomen and others were "very successful business owners".
"I think we have a sufficient cross-section of society to reach an informed and rational decision on the way forward."
"We will not be entering into any further correspondence with you," Hickey added.
Aulakh was unhappy with the response but said it had not dampened his resolve.
Aulakh said he would be "keeping up the pressure".
"I want to make this really clear. I am not out to try to demonise the club. I'm not trying to set out to make them a target of outrage and ridicule," he said.
He was "blown away" by the 120 signatures he had collected since the petition started online on Wednesday.
The decision followed the international outcry over the death of George Floyd, an unarmed black man who died while being restrained by police in Minneapolis last month, prompting Black Lives Matter protests around the world.
