In September 2026, first-home buyers purchasing with under a 20% deposit (>80% LVR) borrowed an average of $633,383, compared with $513,208 for those with a 20% or greater deposit (≤80% LVR)—a difference of $120,175.
Official dataRBNZ Table C31 (September 2026): >80% LVR FHB = $850m across 1,342 borrowers; <=80% LVR FHB = $680m across 1,325 borrowers (dollar series rounded to $1m).
HLF calculation
($850m × $1m ÷ 1,342 = $633,383) minus ($680m × $1m ÷ 1,325 = $513,208) = $120,175 (subject to RBNZ $1m rounding)HLF interpretationHLF market context: The data shows that first-home buyers at >80% LVR take out larger mortgages on average than those at <=80% LVR. RBNZ Table C31 does not record property purchase prices or borrower motivations; factors can include borrowing a higher percentage of the purchase price, regional price mix, or household income.

| Definition | HLF-derived comparison of the mean approved mortgage size for New Zealand first-home buyers at >80% LVR (under 20% deposit) versus first-home buyers at <=80% LVR (20%+ deposit). |
| Methodology | Derived from RBNZ Table C31 by dividing total monthly dollar lending in each LVR tier (published by RBNZ in rounded $ millions) by the exact number of approved first-home borrowers in that same LVR tier. |
| Current value | $633,383 at >80% LVR vs $513,208 at <=80% LVR (+$120,175) |
| Comparison / Prior period | September 2025 ($638,955 vs $516,892) • $120,175 difference between LVR tiers |

| HLF calculation | ($850m × $1m ÷ 1,342 = $633,383) minus ($680m × $1m ÷ 1,325 = $513,208) = $120,175 (subject to RBNZ $1m rounding)Formula: (>80% LVR FHB NZDm × $1m ÷ >80% LVR FHB Borrowers) minus (<=80% LVR FHB NZDm × $1m ÷ <=80% LVR FHB Borrowers) |
| HLF interpretation | HLF market context: The data shows that first-home buyers at >80% LVR take out larger mortgages on average than those at <=80% LVR.

How Dates Are Recorded in HLF Pulse (4-Field Date Standard)
To prevent confusion between when an economic activity occurred and when a government agency published its release, every HLF Pulse record separates four distinct date fields:
| Date Field | Definition & How It Is Populated |
|---|---|
1. Observation period (observation_period) | The period the underlying statistic relates to (for example, September 2026 for monthly RBNZ lending, or Year ended 31 March 2026 for the FMA KiwiSaver Annual Report). |
2. Period end (period_end / as_of) | The final calendar date covered by the observation period (for example, 2026-09-30 or 2026-03-31). Used by HLF’s automated freshness gate to verify series currency. |
3. Source publication date (source_published) | When the original organisation released the statistic (for example, 2026-09-10 for the FMA’s 2026 KiwiSaver Annual Report, or the Published Date recorded inside RBNZ’s workbook metadata). HLF never copies period_end into source_published; where an agency page does not state an exact release date, the agency’s publication schedule is stated explicitly. |
4. Last checked (last_checked) | The date HLF’s automated pipeline last fetched and verified the official source. |
Data Quality & Limitations
- Official published sources: Pulse uses official published data from the Reserve Bank of New Zealand (RBNZ), Stats NZ, Inland Revenue (IRD), the Financial Markets Authority (FMA), MBIE Tenancy Services, the Natural Hazards Commission Toka Tū Ake (NHC), and the Accident Compensation Corporation (ACC) wherever available.
- Unaltered official figures & source rounding: HLF does not alter or estimate official source figures. Where official tables publish rounded aggregates (such as RBNZ dollar series rounded to $1m or $0.1m), derived averages and implied counts reflect that source rounding and note it explicitly in the provenance layer.
- Provenance & derivation layer: To keep the primary editorial summaries natural and readable, exact formulas, series IDs, and derivation labels (Derived by HLF Pulse) are recorded in the expandable provenance layer, Data Dictionary tables,
pulse.json, andllms.txt. Long-term 5-year and 10-year series report both nominal growth and CPI inflation-adjusted (real) growth using Stats NZ’s Consumers Price Index. - Price indices vs. individual quotes: Stats NZ CPI insurance sub-indices measure percentage changes in standardised insurance price indices over time—they do not represent the dollar premium quote for an individual property or policyholder.
- Separate claim counts vs. individual proportions: In the ACC dataset, annual weekly compensation claims and total accepted injury claims (which are mostly minor treatment-only visits) are reported as two separate annual claim counts rather than a proportion of injured individuals.
- Commitments vs. settlements: RBNZ mortgage lending tables (C31, C32, C33, C40, C41) measure firm bank mortgage commitments/approvals rather than LINZ property title settlements.
- Automatic staleness exclusion: HLF automatically excludes any series where the underlying source is unavailable, stale past its freshness window, or cannot be verified.
- Market context vs. individual outcomes: Statistics describe aggregate historical market cohorts and do not predict an individual borrower’s, saver’s, or policyholder’s credit assessment, underwriting, or lending outcome.
