The Sharesies Index of investor confidence averaged 38 in the September 2026 quarter, down from 57 in the June quarter, as the Reserve Bank of New Zealand raised the official cash rate twice and annual CPI inflation hit 4.1 percent driven by higher fuel prices.
ASB’s Q2 2026 Regional Economic Scoreboard left Wellington joint last with Gisborne while Canterbury led on dairy cash, jobs and retail. The capital’s multi-quarter underperformance is structural: public-service consolidation, a deep housing correction and stalled population growth colliding with a national OCR still set for nationwide inflation.
Economists expect New Zealand’s June quarter GDP to rise just 0.1–0.2 percent when Stats NZ reports on 17 September, a sharp slowdown from March’s 0.8 percent gain as elevated oil prices compress real incomes.
Finance Minister Nicola Willis has refused the Reserve Bank’s first bid to roll $10.1 million of 2025/26 underspend into 2026/27 and published three criteria that will govern every future variation under the 2025–30 Five-Year Funding Agreement.

Retail investors on the Sharesies platform showed measured caution rather than panic in the September 2026 quarter. The platform's proprietary index fell to an average of 38 from 57 in the prior period. This reading returns sentiment to levels last seen two years earlier and places it firmly in the cautious category.
The drop coincides with the Reserve Bank of New Zealand resuming its tightening cycle. The OCR rose 25 basis points to 2.50 percent in July 2026 and another 25 basis points to 2.75 percent on 2 September 2026. The central bank cited June quarter CPI inflation at 4.1 percent, the highest annual rate in over two years and well above the 1-3 percent target band. Stats NZ data show the surge stemmed primarily from higher fuel and transport prices linked to Middle East disruptions.
Sharesies general manager of Wealth Scott Nixon highlighted resilient underlying flows. Investors remained net depositors even as they tilted toward diversified global ETFs rather than pure US exposure or outright withdrawals.
So, we had a deposit ratio, a net deposit ratio averaged about 2.08, which means roughly that for every dollar that's withdrawn from Sharesies platform, just over $2 was deposited.
The drivers
The RBNZ's September 2026 Monetary Policy Statement emphasised gradually removing stimulus to anchor inflation by late 2027. Treasury data showed real GDP grew 0.2 percent in the June 2026 quarter, with annual growth at 1.7 percent. Export sectors remained resilient while domestic consumption and Auckland/Wellington housing markets stayed soft.
The Reserve Bank raised the OCR twice this quarter, to 2.75 percent, citing 4.1 percent annual inflation driven largely by fuel prices.
Global market volatility added pressure. The platform recorded a shift away from concentrated US holdings toward broader 'total world' ETFs. Top holdings stayed stable, led by Smart US 500 ETF, Rocket Lab, Vanguard S&P 500 ETF, Air New Zealand and Nvidia. Fonterra Shareholders' Fund gained 18 percent and entered the top 10 most-held investments.
NZX performance offered mixed signals. The S&P/NZX 50 Index rose 1.6 percent over the September quarter, closing around 13,834 points. Standouts included Hallenstein Glasson up 48 percent and Fonterra Shareholders' Fund up 24 percent. Retirement village stocks and rate-sensitive names lagged as bond yields rose.
The NZX 50 rose 1.6 percent over the September quarter even as Sharesies' retail investor confidence index fell, reflecting diverging signals between listed-market performance and household sentiment.
The trade-offs
Higher OCR rates anchor inflation expectations but compete directly with equity markets for household savings. Term deposit rates have risen through bank pass-through, rewarding savers and reducing inflationary demand. This maintains RBNZ credibility.
The cost appears in capital rotation from productive equity investment into bank deposits. This could slow capital formation for listed New Zealand firms and reduce NZX liquidity. Diversification into total world ETFs reduces single-market risk for households but further internationalises savings, reducing domestic equity inflow support.
Retail investors maintaining net deposits at a 2.08 ratio while reducing risk appetite keeps platform assets under management stable. Yet marginal new capital parks in lower-risk instruments, meaning growth-oriented NZX and ASX listings receive less fresh capital than in prior quarters.
Second-order effects
NZX liquidity faces pressure in rate-sensitive sectors. Retirement village operators and property-related names already lagged in the September quarter. Sustained cautious retail sentiment reduces marginal buyer support, amplifying yield-driven valuation compression.
Bank deposit bases expand as retail investors shift toward term deposits. Major banks improve funding stability ratios, potentially at the cost of equity market depth.
KiwiSaver wealth effect feedback loops could emerge. If equity market underperformance persists in rate-sensitive sectors, balances grow more slowly. This reduces the household wealth effect that supports domestic consumption, already flagged as soft by Treasury.
US tech-NZ retail linkage amplifies external volatility. Rocket Lab and Nvidia rank among top holdings. Any US equity repricing driven by Fed policy or earnings would register directly in subsequent Sharesies sentiment scores.
Slower capital formation in deep-tech and space sectors could follow. A sustained period of cautious sentiment reduces secondary market support for high-multiple growth names. Rocket Lab's visibility on the platform serves as a retail confidence signal for New Zealand's innovation economy.
Historical context
The 2022-2023 RBNZ tightening cycle saw retail platform sentiment fall sharply as the OCR rose from near-zero to 5.5 percent. Net deposit ratios remained positive throughout. Sentiment recovered once policy clarity on the peak rate emerged.
The current cycle mirrors that pattern but starts from a lower OCR and features a supply-shock inflation driver from fuel rather than demand-driven pressures. In 2022-23 housing market correction was the primary wealth-effect channel. Auckland and Wellington housing markets are already soft, so the incremental negative wealth effect from further rate rises may be smaller, though household balance sheets start more stretched.
A prior Sharesies dip to 45 in the March 2026 quarter recovered to 57 by June once geopolitical uncertainty eased. The index responds strongly to policy and geopolitical clarity events. The October 2026 RBNZ review therefore represents a near-term catalyst to watch.
The counter-argument
Some observers may read the 19-point drop as evidence of eroding retail faith in New Zealand equities. The headline confidence collapse could signal broader withdrawal from risk assets amid persistent inflation and rising rates.
The data supports a different reading. Net deposits remained positive at 2.08 while trading volumes stayed healthy in prior quarters. Investors adapted by diversifying and pausing new commitments rather than exiting positions. This matches the pattern seen in 2022-2023 where sentiment stabilised once the OCR path clarified.
Open questions
Whether the OCR peaks at or near 2.75 percent or pushes higher through the December 2026 Monetary Policy Statement remains unclear. Next decisions are scheduled for 28 October 2026 and 9 December 2026.
Election-related caution noted by Sharesies executives adds a domestic policy overlay. Investors await clarity on fiscal settings before committing fresh capital.
Forward outlook
The durability of retail composure depends on inflation persistence and the RBNZ's December 2026 statement. Treasury forecasts of a broadening recovery in the second half of 2026 could support stabilisation if fuel price pressures ease. Persistent inflation risks may prolong higher-for-longer rates, affecting KiwiSaver balances and household wealth effects. Households continue adapting rationally to the policy environment rather than exiting markets outright.
