RPNZ works hard to ensure our data is accurate and up to date. But what should you do if you find any data you think is wrong? It depends on which data point you’re looking at.
Rating valuations are conducted every 3 years to help determine council rates. Different bodies are responsible for different datasets: the QV Group manages a large volume of New Zealand’s rating valuations data, while OPTEON and local councils manage some areas.
To confirm who is responsible for a particular rating valuation, contact the relevant local council.
Sales data in RPNZ is provided by Land Information New Zealand (LINZ).
When a property is sold, the solicitor involved in the sale must report the transaction information to the local council, who then updates the District Valuation Roll and LINZ. So if a sale is missing from the CoreLogic database, it may still be going through this process.
If you’re not sure, contact CoreLogic Customer Support on 0800 355 355 to ask us to check the sales data sources. We can find out why the data isn’t available yet and what the next step might be. Unfortunately, we can’t correct this data ourselves as the solicitor needs to provide it.
Provisional sales data
In RPNZ, provisional sale prices for properties are displayed in purple. This dataset is sourced directly by CoreLogic’s Recent Sales team, who contact agents each day to retrieve this data before it’s officially registered with LINZ.
When a property sale is settled or registered with LINZ, the price in RPNZ changes from purple to black to show that it’s the official sales data.
Informing us about data issues
If you find any data that's incorrect or out of date, contact CoreLogic’s Customer Support team by submitting a data update within RPNZ.
The data team will investigate issues relating to:
- details of a provisional (recent) sale
- an incorrect property listing
- a property’s number of bedrooms or bathrooms
- property photos and other imagery
- suburb statistics data (demographic data is derived from the government census)
- legal information, such as incorrect legal details against a property’s address.
