KEY POINTS:
Officially, Howick is the new electorate created in Auckland under proposed new boundary changes announced yesterday but, from a political perspective, the new electorate may be Papakura because no MP has a clear claim to it.
Both parties consider it a marginal seat on paper at least and it will be hotly contested.
Population shifts to the southeast of Auckland have forced a major redrawing of the boundaries, although they have little effect on the overall election result under MMP.
Justice Minister Mark Burton is expected to lose his Taupo seat and National maverick Brian Connell will have no seat to stand in.
Changes may also favour National in Rotorua, which is held by Labour's Steve Chadwick.
Clevedon will disappear but its National MP, Judith Collins, is expected to claim the right to stand in Howick.
And while Port Waikato disappears, its National MP, Paul Hutchison, will likely claim the right to stand in the newly formed Hunua.
Labour list MPs Dave Hereora and Darien Fenton have offices in Papakura.
Old names have been scattered across the redrawn electoral map with Howick, Hunua and Papakura in the North Island and Waitaki and Selwyn in the South Island being revived.
As expected, the falling populations down south have pushed the boundaries of South Island electorates north, squeezing out Mr Connell.
Despite speculation Mr Burton might retire at the next election, he made it clear last night that he intended to stand again.
He said whatever the final boundary changes, "I am happy to continue to be judged on the work I do for and on behalf of my constituents".
In geographical shifts, Raglan finds itself part of Taranaki-King Country and the Waikato town of Cambridge finds itself in the Taupo electorate.
The major change in the Maori electorates is the proposed name change for Tainui to Pare Hauraki-Pare Waikato.
That was also recommended in 2002 under draft changes but was dropped in the final version.
