Statiscs New Zealand has updated its CPI basket components, a project it does every three years.
Food and housing are weighted a little higher in this new review. Heath, transport and communication costs are weighted less.
"More people are going online to buy shared ride services, such as Uber, and shared accommodation services, like home-rental operators Airbnb and BookaBach," prices senior manager Jason Attewell said.
"We’re introducing the sharing economy to the CPI to keep it relevant for New Zealand."
"People are changing what they buy to keep up with changes in technology, and as a result, we’re removing several items from the CPI basket. These items are still available to buy, but New Zealanders just don’t spend as much on them."
As a result of the 2017 CPI review, things like in-car sat-nav systems, DVDs and BluRay, MP3 players are all out.
"At the same time, we’re seeing increased spending on technology accessories like headsets and cellphone cases. We’ve added these items to the CPI basket as part of the latest review."
"The CPI basket is really a reflection of New Zealand society and how it has changed over time," Attewell said.
"We added the electric lightbulb to the basket in the 1920s, televisions and record players in the 1960s, microwaves and car stereos in the 1980s, and MP3 players and digital cameras in the 2000s. As these items go out of fashion they are removed from the basket."
|Group||Base expenditure weight|
|Alcoholic beverages and tobacco||6.96||7.00|
|Clothing and footwear||4.21||4.28|
|Housing and household utilities||24.23||24.47|
|Household contents and services||4.65||4.46|
|Recreation and culture||9.40||9.51|
|Miscellaneous goods and services||7.28||8.02|
Housing and food remain the most important items in the basket, accounting for almost half of people’s spending. Housing includes rent, new builds, and other house improvements.
And because it is of special interest to some readers, here is an extract of the Housing components:
|Group, subgroup, or class||September 2017 quarter base expenditure weight|
|Percent of total expenditure (weight)|
|Housing and household utilities group||0.65||23.82||24.47|
|Actual rentals for housing||…||9.12||9.12|
|Purchase of new housing||…||5.42||5.42|
|Property maintenance materials||0.55||…||0.55|
|Property maintenance services||…||1.68||1.68|
|Property rates and related services||…||3.56||3.56|
|Refuse disposal and recycling||…||0.13||0.13|
|Local authority rates and payments||…||3.05||3.05|
|Other property related services||…||0.02||0.02|
People are also spending more on craft beer and massages, so these are joining the CPI basket too.
"New Zealand used to be called a country of rugby, racing, and beer – but spending patterns are changing and Kiwis are increasingly keen on craft beer, body massages at beauty spas, and football club memberships," Attewell said.
At the same time, sewing machines are out of the inflation basket, but clothing alterations are now in.
"People don’t have as much time to do things themselves, and are prepared to pay others to do jobs for them," Attewell said.
Stats NZ reviews the CPI basket of goods and services every three years to ensure it remains relevant. This is done by surveying people to find out what they spend their money on.
