After Mana president Annette Sykes said she was concerned the party was proving to be "fragile" over the issue, Mr Harawira said he accepted that not everybody in the party was going to agree on a deal with the Internet Party.
"Will there be resignations? Quite possibly. There haven't been today. I'm not that fussed about it.
"There's always going to be people who come in and out for various reasons and that's fine."
Asked whether he thought the deal would go ahead, Mr Harawira said: "I'd certainly like to think so."
A final decision is likely to take a further month. Agreement is needed on the mechanics of the deal, on policy bottom lines between the two parties and on who Internet will field as candidates.
Mr Harawira indicated the final decision would be made by senior party figures rather than a wider vote.
"It will probably be made by the executive in the final analysis."
Ms Bradford last night said she would consider her future with Mana once a final decision was made.
Former InternetNZ head and Internet Party chief executive Vikram Kumar said there were several areas of common ground with Mana.
"There is definitely a common interest of changing the National Government, and there is a common interest in economic development, particularly for young Maori and in the rural areas."
While the two parties are still in the early stages of understanding how their possible alliance could work, Mr Kumar stressed that neither party had to give up their sovereignty.
"It was never meant to be looked at as a merger."
The vote on proceeding with the Internet Party talks came after Mr Dotcom put his case to about 200 Mana members on Saturday.
While they continued their meeting at Rotorua's lakeside Mataikotare Marae yesterday, more than 700 Internet Party members convened pool-side and on the expansive lawns at Mr Dotcom's Coatesville mansion, where they heard from Mr Dotcom on how they could be a part of the policy-making process.
In Rotorua, Mana heard from another multi-millionaire, Gareth Morgan, who said Maori were suffering under a regime of "ethnic disadvantage".additional reporting, Mohamed Hassan
