Sixteen electoral wards of the Christchurch City Council, each elects
one councillor: grouped under six community boards, under a mayor
elected at large: Phil Mauger,
returned October 2025. The suburbs each ward centres on,
who holds the seat, and the record inside its boundary.
What the record says
Banks Peninsula holds the most suburb centres, 25 of them, and the fewest voters to pick a councillor from: 7,613 electors where an even draw would give ~17,547.
Central keeps the fattest file, 85,595 reports on record, 17 times Waimairi's 4,944.
Every other board spans several wards; Banks Peninsula keeps a whole community board to one ward, 25 suburbs under it.
The city, divided for elections
The council’s own electoral boundaries: hover or
follow a shape to its ward. The suburb roll maps to wards by centre
point: an address near an edge can sit in the neighbouring ward.
MyCouncilTicket, the council’s own work orders,
not the resident reports above. Fastest first; a median counts only
jobs that finished, so open work is never averaged in.

Sixteen seats, drawn to be even
The wards were drawn to carry
about the same share of voters, an even split is
~17,547 electors a seat. The outliers tell their own
stories: Banks Peninsula keeps its own seat on 7,613
electors because the harbour and the hill bays are one community of
interest the rule can’t split, and the growth suburbs have outrun
the draw: Halswell now enrolls 21,168.
Papers returned as a share of enrolled electors,
the electoral officer’s own count. The peninsula’s papers come back
at twice Riccarton’s share, the geography of who votes local.
The boundaries are the council’s own
electoral
layer, joined to the suburb roll by each suburb’s centre point,
ward edges don’t always follow suburb lines. Prebbleton, Tai Tapu are in the suburb
roll but outside the city entirely: Selwyn district, which elects
its own council.
The mechanics: how community
boards work · how councils
work.
