Population – a view of the whole national

As our population reacts to the environment of COVID-19, there is evidence of large increases in movement around New Zealand. Because of that, it’s now worth looking at our country as a whole. To do that we have highlighted international and domestic population numbers, as well as our national mobility index^[*] as we continue through COVID-19 Alert levels.

To help explain what the numbers mean below, we describe domestic population as someone who is outside of their local tourism region. These regions areas are defined by Regional Tourism Organisations.

Our population – average population

As we all settle into what is a new set of habits, it's important we understand what these new habits look like.

On this page of the report we have sampled average hourly representations of population estimates in New Zealand around six key areas across COVID-19 in New Zealand. We have used the population patterns previous to COVID-19 to identify these areas. Refer to our notes^[*] at the end of this report to understand a bit more detail of what each areas/behaviours of New Zealand these graphs represent.

Our population – before COVID‑19 and now

By looking at hourly population counts^[*] across the country, we can get a good idea of how behaviour has changed in response to COVID-19. The data presented here uses hourly population counts for six types of areas^[*] in New Zealand - retail, transit, residential, tourism, workplace and recreational.

In this part of the report, we cover off three periods: A normal week in 2019^[*], two weeks ago, and one week ago. We have broken out the comparisons into one comparing last week to a normal week in 2019 to see what change happened compared to last year, and the other comparing what has happened over the last two weeks. From doing this, these are the insights we have discovered.

Uses of these insights: The comparison to a normal week in 2019 can be used to offset other datasets designed prior to COVID-19. The figures contained in this report could be used to make adjustments to previously known datasets values. For the two week comparison, it allows you to measure a sentiment of change over a shorter period. Footnotes

Our population – mobility during COVID‑19

In this section we explore mobility index for the population of New Zealand in six key categories^[*] during COVID-19.

Our mobility measure^[*] is created using the difference between maximum and minimum population estimates in categories of New Zealand over a day. This allows us to get an idea of mobility between each day of 2020 in this report compared to similar days from 2019.
