Labour's Waitakere candidate Carmel Sepuloni had plenty of fans in Glen Eden, Kelston and Ranui - but National's Paula Bennett pulled in the votes in Henderson, Swanson and Titirangi.
It was a close race between the two candidates and although Ms Bennett got the most votes with a 349 majority, more than 3400 special votes are still to be counted, which could make a big difference.
It seems that final result might just come down to what suburb people making the special votes are from, as the two leading candidates appear to have more fans in some areas than others.
After analysing the preliminary voting result for the Waitakere electorate, it is clear some suburbs have strong political links and voters have swung strongly towards Ms Bennett or Ms Sepuloni.
In Henderson's 11 voting centres Ms Bennett pulled in just over 4100 votes - 858 more than Ms Sepuloni.
