Debt to Income Series description

Total Debt to Income ratio (TDTI)

Total Debt to Income ratio (i.e. Total Balance of Borrowers’ Debts (to all lenders) / Total Gross Income).

Total balance of loan values is the sum of all loan values (typically the limit of each loan) that the borrower or borrowing parties discloses they are responsible for servicing out of their income. This includes the loan value of the new commitment, and any pre-existing mortgages, although there are some debts that are typically excluded, such as business and student loans.

Unknown DTI

Borrowers and loans classified as “unknown DTI” are extraordinary cases where the information on borrower debts or borrower gross incomes are incomplete, unverified or not recoverable, and no reasonable proxy exists to estimate the DTI. Proxies must reflect information specific to the individual customer.

Unknown DTI's are included where DTI 'bucket' is not specified.

Borrower Gross Income (BGI)

Borrower gross income is the amount a bank is prepared to count in its servicing analysis (i.e. that qualifies (after any applicable haircuts) based on internal policy). It includes wages and salaries, self-employment income, boarder income, rental income, superannuation & other government benefits and investment income.

Loan to valuation ratio (LVR)

Loan-to-valuation ratio = [loan value / property value] x 100.

New commitments ($ millions)

Value of committed residential mortgage loans during a month, which are finalised offers to customers to provide mortgage loans or to increase the loan value of an existing mortgage loan, as evidenced by the loan documents provided to the borrower. Any offer to purchase a home by the customer, that is to be financed by the loan, is typically unconditional at this stage.

First home buyers

A first home buyer is a borrower intending to purchase or build a property for owner occupation in New Zealand for the first time. In the case of more than one borrowing parties to a loan, borrowers are classified as first home buyers only if none of the borrowing parties have previously drawn down on housing finance for owner occupation. If the borrower, or at least one borrowing party, has previously drawn down on housing finance for owner occupation they are classified as "other owner occupier".

Other owner occupier without investment property collateral

Other owner occupiers are borrowers who own or are in the process of buying or building a house or flat they (or a related party) will live in, are borrowing against properties that meet that definition, are not first home buyers, and are not borrowing against any investment properties. An owner can occupy more than one property, e.g. a family home and a holiday home.

Auckland commitments

This includes any loan that has any Auckland investment property as collateral. It also includes any loan that has an Auckland owner occupied property as collateral, unless that loan has also has investment property as collateral and those investment properties are all outside Auckland.

Borrowers (number)

Number of monthly committed residential mortgage loans, which are finalised offers to customers to provide mortgage loans or to increase the loan value of an existing mortgage loan, as evidenced by the loan documents provided to the borrower. Any offer to purchase a home by the customer, that is to be financed by the loan, is typically unconditional at this stage.
