Mr Lotu-Iiga said he grew up in the Mangere community and was once too a Labour voter, but he had been seeing a shift in support towards National. "Things are changing around here."
Also at the meeting was Manukau city church group member Del Kumandan, who said he too had seen National's support grow in the area.
"The tide's definitely turning?the people are identifying with what National is doing for them."
However, not all were as convinced.
Robert Ramsay said he had previously been a Labour voter, but had become disillusioned with the political process and wasn't planning on voting in November's general election.
"I used to be a hard-core Labour voter but then I just stopped voting...I'm just not really interested in politics anymore."
Christina Pauu-Tonuga said National was still seen as promoting a "rich man's world".
"There's still a lot of poverty and I don't see much change happening."
Yet Prime Minister John Key said there had been a shift in support in the Labour stronghold of South Auckland.
"We've been saying for quite some time that we see a shift in the Pacific voting patterns.
"I can't think of a time when I've been the leader of the National Party when we would have had so many people in Mangere turn up for a National Party meeting .
"I think it just sends a very strong message that there are changes afoot in voting patterns for Pacific New Zealanders.
"Our big job now is to make sure that come the polling day they do turn up and they do cast their party vote for National."
The Pacific community had been identifying with National Party values more after coming to New Zealand and originally finding work in low-skilled, unionised jobs dominated by the Labour movement, Mr Key said.
"We're still very much the underdog with Pacific voters and also, in South Auckland, but I think we are going to do better in this election then we've done in the past."
