The overall age of submitters was also significantly older than Auckland's general population - seven out of 10 submitters were above the median age of 34.
Generation Zero spokesman Leroy Beckett, whose organisation encourages younger people to get involved in local government decisions, said the data did not surprise him.
"Anyone who's worked in consultations and local government or has even been to a council meeting, the kind of demographics you see there are reflected in that data."
The council should consider adopting models used overseas, such as citizens' juries - forms of which existed in Ireland and Toronto, Canada, he said.
The local board area with the lowest rate of feedback on the plan was low-income, ethnically-diverse Māngere-Ōtāhuhu, where just 310 people - 0.4 percent of the population - made a submission.
That compared to 1.3 percent across Auckland and 3.1 in Rodney, which has a predominantly Pākehā, older-than-average population.
A closer analysis of the data revealed that even within Māngere-Ōtāhuhu, the predominant ethnicity - Pacific people - made fewer submissions than Pākehā, who only make up 18 percent of the area's population.
Favona resident Deepa Raj said there was a low level of awareness among her fellow residents - particularly Pasifika people like herself - about how they could even have a say.
"We have a lot of opportunities to raise our voices, to have a say, but most of our people do not know where to go… It's also our culture that we're not taught to raise our voice."
Māngere-Ōtāhuhu local board chair Lemauga Lydia Sosene said the way the council gathered feedback often did not take into account the cultural diversity of her area.
"When you look at the figures of who actually submits in a council process, there's very few numbers, that [do] not fully reflect the people from this area."
Auckland Council engagement manager Kenneth Aiolupotea told RNZ not all of the 100 or so consultations the council ran in 2018 attracted the same demographic and the Auckland Plan 2050 feedback should be treated as a snapshot in time.
"That was the first part of the conversation and our challenge now is to say, well, given that was the exploratory phase … we are clear about the broader context of where we want to take Auckland, how do we make sure that Aucklanders, particularly those groups that weren't as involved in that first step, are more involved going forward."
Using social media and online surveys, developing relationships with leaders of minority communities, and gathering feedback at community events were all ways the council was trying to gather more diverse views, Mr Aiolupotea said.
However, Wellington-based public policy researcher Jess Berentson-Shaw said the time and energy needed to participate still excluded many people.
"Consultation's pretty old-hat, and we should be moving towards much more engaged and participatory and shared decision-making models on these kinds of issues."
That meant involving people right at the very start to help define the problem, and removing financial and other barriers to participation, she said.
"If you're designing a city for older, Pākehā, well-off people, when we know that the city does not look like that now - and it is sure not going to look like that in the future - you're planning and putting in place massive problems for yourself."
