‘Unique’ meant each person was only counted once in each area they appeared, regardless of how many times they appeared or how long they stay there.

The series began in January 2019 and aimed to fill a key gap that was identified by the tourism sector in understanding regional visitor volumes.

The populations that were estimated included:

• International visitors – people from outside New Zealand who are stayed in the country for less than 1 year.
• Short-term international visitors – a subset of international visitors who stayed in the country for less than 90 days. (These people are counted as both ‘international’ and ‘short-term international’).
• Local residents – New Zealanders in their primary or secondary home region.
• Domestic visitors – New Zealanders outside their home region(s).

Anonymised mobile location data used

To produce the MURPEs, Data Ventures used anonymised data from telecommunications data providers that contained anonymised information about mobile phone locations. They then applied a weighting process to account for people without a phone or with multiple phones.

A Privacy Impact Assessment was been completed to ensure the methodology complied with the Privacy Act 2020 and did not pose any risks to individuals.

Commuters are removed from the visitor population

Commuters are classed as people who appeared in both their home region and another specific regional tourism organisation (RTO) area on the same day, at least 25% of days. This definition was tested and agreed upon with a group of key stakeholders from the tourism sector.

To distinguish between local residents and domestic visitors, each phone was given a ‘home region’, which is the RTO area where it most commonly appeared. Regular commuters were assigned a second ‘home region’ where they were classed as local residents and not domestic visitors.

RTO areas were defined based on the 2020 boundaries from Stats NZ.

MURPEs figures are estimates and have limitations

Some key limitations of the MURPEs include:

• Figures are estimates and are best used to monitor trends rather than exact figures.
• Unique visitors are counted the same, regardless of their length of stay.
• International visitor numbers for the most recent 3 months are provisional and subject to change.
• People who engage in tourism activities within their home region(s) will not be counted as domestic visitors.
• The RTO numbers should not be summed up to get a total for a set of several RTOs. This is because 1 individual can be counted in multiple RTOs, and therefore will be counted multiple times.
