The data: coverage, periodicity, and timeliness

Coverage characteristics

Data is sourced from the Credit Card Survey. The survey covers credit and charge cards.

The survey defines credit and charge cards as those that can be used to make purchases and obtain credit at all merchants accepting branded credit and charge cards in New Zealand and overseas. It is different from a store card with brand logos (e.g. GEcreditline, Qcard, Farmers Card), which can only be used at a limited number of merchants. Store cards are not in scope of the survey.

A credit card enables a cardholder to access a revolving credit facility. The cardholder can use the card to make transactions up to a pre-arranged limit.

A charge card enables a cardholder to access a non-revolving credit facility. Charge cards often do not have an explicit credit limit.

Data are published in millions of New Zealand dollars. The data are both daily averages and ‘as at’ the last day of the month, with interest rate information on both bases.

Data series begin January 1981. Credit card billings (table C13) covers credit card spending in New Zealand and overseas as well as spending in New Zealand by overseas issued cards.

Year on year changes are based not on the actual total $m but a monthly series corrected for seasonality and trading day effects.

Selected credit card information is published for registered banks in S32.

Seasonal adjustment

Most data series collected in the credit card survey are affected by seasonal factors, for example national holidays and festivities, the timing of school holidays, and the number of trading days in the month. The existence of such seasonality makes month-to-month comparisons difficult. Seasonal adjustment is the process of estimating and removing the usual seasonal effects from a time series in order to reveal the underlying non-seasonal features.

The Reserve Bank seasonally adjusts data in the credit card survey using X13-ARIMA.

Seasonal adjustment practices

  • A pre-defined adjustment model chosen on statistical merit is used for each series.
  • An adjustment is run on the entire series as each new observation becomes available (concurrent seasonal adjustment method)
  • Where a series is an aggregation of multiple series, its seasonally adjusted values are calculated from the total series, independent of the separately adjusted sub-series (direct adjustment)
  • Where seasonality is not significant, the seasonally adjusted series is set equal to the actual values over the indicated time span.

Advances 90 days past due

This is the value of advances outstanding (or credit card debt) that is older than 90 days. This time series enables analysis of the ability or willingness of credit card users to repay debt.

Balances Outstanding

This is the amount of money, either on deposit for, or owed in total by, all credit card holders as at the end of each month. This includes both active and inactive accounts, but no closed accounts.

Credit Limits

This is the total value of all cardholders' credit limits at the end of the month for credit cards able to be used for spending (‘unblocked' cards). A credit limit is authorised by the issuer for total credit a customer may have outstanding on a card without being in breach of the agreement with the issuer. For some cards this will be zero.

Credit limit utilisation

Credit limit utilisation is calculated as the ratio of total advances outstanding (or credit card debt) to total allowable credit limits.

Personal card total advances outstanding

All borrowing outstanding on personal cards, calculated as a daily average for the month, is included here.

Personal card interest-bearing advances outstanding

Interest-bearing advances outstanding is the amount of credit outstanding on which interest is being charged to the customer, calculated as a daily average.

Personal card non-interest bearing advances outstanding

Non-interest-bearing advances outstanding is the amount of credit outstanding that does not have interest being charged to the customer, calculated as a daily average. This amount corresponds to the `free float' that exists as a result of the `interest free days' arrangements made by issuers for most cards. It is estimated using a formula agreed with issuers. This section also includes any 0% balance transfers offered to customers.

Simple average interest rate on personal `classic' cards

The interest rate charged on the standard, or `classic' card, usually the most commonly held, is reported as a simple average among the nine issuers with such cards.

Weighted average interest rate on personal interest-bearing balances

Where interest is being charged to the customer, the daily weighted average of such rates is reported here.

Weighted average interest rate effective on all personal balances

The calculation of this rate takes as denominator both the daily average balances of credit card balances paying interest and the `free float' on credit and charge cards, with revenue from interest payments as the numerator. The resulting interest rate is called the `effective' interest rate.

Amounts financed

These comprise spending by credit card holders and cash advances received during the month concerned, both on cards issued in New Zealand and issued overseas. `Billings' means spending on a card, or `amounts financed' - the monthly flow of total card debits (excluding interest), either by direct purchase or via cash advances. The rates of growth of billings are based on seasonally-adjusted data, which allows for trading day effects.

Total billings in New Zealand

This is the spending within New Zealand by holders of cards issued in New Zealand and overseas-issued cards.

Total billings on cards issued in New Zealand

This total adds New Zealanders' domestic card spending to their card spending overseas (billings overseas).

Changes to seasonal adjustment models

21 September 2021

We advised on 21 May that we were reviewing seasonal adjustment practices for credit card billings statistics. We have now reviewed seasonally adjusted series for credit card billings and balances series. New seasonal adjustment models have now been applied, including to historical data. The new models are specified on the Background Notes tab of this page.

These changes will better capture seasonal patterns and make seasonally adjusted series more comparable between time periods.

For more information about the review of seasonal adjustment practices see Technical note on seasonal adjustment review (May 2021).
