Population boom planning queried


New Zealand’s population has grown by more than 100,000 over the past year.
The record growth in the year to July brings the population to 4.79 million, Statistics New Zealand said yesterday.
The bulk of the increase was people who were migrating (72,300), while births made up 28,100 new residents.
While most migrants were arriving on short-term work and student visas, many of them extended their stay, adding to the population figures, population statistics senior manager Peter Dolan said.
Half of the total increase was made up of people aged between 15 and 39.
This age group now made up 34% of New Zealand’s population, down from 41% in the mid-1980s.
Meanwhile, the number of people aged over 65 had increased by more than 25,000 in the last year, with more than 30,000 people now aged 90 or older, Statistics NZ said.
It is estimated the number of over-90s will reach 50,000 by the early 2030s.
Economists warn the 100,000-person surge over the past year is putting more strain on the country’s infrastructure and housing, RNZ reported.
They say the population growth has come at a great cost.
Michael Reddell, an independent economic commentator, said the high levels of immigration did not mean New Zealand would be better off, as many would end up working in industries that did not add to the country’s export earnings.
“It’s undermining the ability of our economy to achieve productivity growth that’s what makes us better off in the long-run. It’s not everything, but it is almost everything,” he said.
“We end up having to devote too much in the way of resources to building houses for each other, when those resources could be better used for building export industries and making us all better off.”
Fellow economist Ganesh Nana said the high levels of immigration had put the country under strain.
“We are reaping the short-term gains from a population boom. Unfortunately I think we are setting ourselves up for some significant negative costs over the longer term,” Dr Nana said.
Those included congestion costs, social cohesion, and trying to catch up on infrastructure, he said.
Dr Nana said he favoured doubling the size of the population to 10 million, although he said the stresses the country was currently under showed the need for a strong plan for population growth.
“The big, missing piece of the jigsaw puzzle in my mind is nobody says, ‘Well, how big are we actually planning for?’,” he said.
“If we put that in the jigsaw puzzle, it makes it a little bit clearer whether the infrastructure is too much or too little and what is missing.
“If we don’t have an idea of how big we’re planning for then it really is a matter of continuing what we’ve always been doing and playing catch-up,” he said.
Dr Nana said a sound plan would also let the country spread its population growth beyond heavily congested Auckland. NZN
