The New Zealand population grew by 214,000 people in the last
seven years, census data released today shows.
The new Statistics New Zealand figures, based on the first
census since 2006, showed that population growth had slowed
compared to the previous census.
Government statistician Liz MacPherson said that on average
the population grew by 31,000 people a year in the least
"This was slower growth than between 2001 and 2006, when the
population grew by an average of about 58,000 per year."
The increase meant that a new electorate would be required in
the next general election, in the North Island.
The total number of electorates would increase from 70 to 71,
while the number of Maori electorates would stay at seven.
"Adding this new electorate means there will be one less list
seat in the 120-seat parliament - excluding any overhang
seats," Ms MacPherson said.

awaited by a huge number of people and organisations, in

The population had grown by 6.6 per cent in the North Island,
compared to 3.7 per cent in the South Island.
The largest growth was in Auckland. Its general electoral
population now exceeded the electoral quota by 18 per cent -
much more than the recommended quota of within 5 per cent.
The Hunua, Helensville and Selwyn electorates had also
exceeded their electoral quota.
The most significant population declines had been in
quake-damaged Christchurch. The Christchurch East electorate
lost the largest amount of voters, followed by Port Hills,
Christchurch central and the East Coast of the North Island.
Populations had swelled on the outer regions of Christchurch,
in particular Selwyn, Wigram and Waimakariri.
