Why is the NZ dollar
so weak?

The New Zealand dollar is weak against the US and Australian dollars. In its 19 October 2026 note, Westpac said the NZ dollar was at a 17-year low on a trade-weighted basis, and NZD/AUD had touched 0.8004, a 13-year low. Westpac links any recovery to interest-rate gaps with the US closing and firmer evidence that New Zealand's economy is recovering.

"Trade-weighted" means against a basket of the currencies of New Zealand's main trading partners, so a 17-year low on that measure means the NZ dollar is weak against many currencies at once, including the US dollar.

Why has the NZ dollar fallen against the US dollar?

Much of the recent movement started in the US. Westpac reported that NZD/USD dropped to 0.5565, its lowest in 18 months, in the week to 19 October, when the US dollar jumped after US inflation data came in hotter than expected. Two days later it rose to 0.5675 as markets scaled back expectations of a US Federal Reserve rate hike.

Interest rates matter too. When New Zealand interest rates are low compared with US rates, NZ dollar deposits and bonds earn less, which tends to weigh on the currency. Westpac's forecast has NZD/USD at about 0.56 at the end of 2026, then climbing to around 0.64 during 2027 as NZ and US interest rates move closer together. The RBNZ's Official Cash Rate is 2.75% (since September 2026), and the next decision is on 9 December 2026: see the OCR page.

Why is the NZ dollar so low against the Australian dollar?

NZD/AUD touched 0.8004 in the week to 19 October 2026, its lowest in 13 years, before softer Australian jobs data lifted it to 0.8150, according to Westpac. That compares with a 5-year average of 0.903 in Westpac's table.

Westpac ties a rebound to New Zealand's own economy. It says a recovery to around 0.83 is plausible if the NZ recovery looks more convincing over the coming months. The same note reports that Westpac had cut its forecast for New Zealand's 2027 GDP growth by 0.3 points to 2.7%, because of higher energy prices and long-term interest rates, after marking 2026 down to 2.5%. See the NZD/AUD forecast for each bank's numbers.

What does a weak NZ dollar mean for New Zealanders?

  • Money sent overseas buys less. NZ$1,000 converted at the mid-market rate was worth A$814 on 11 Nov 2026, against A$866 on 11 Nov 2025 (our arithmetic on ECB rates). Banks and transfer services give less than the mid-market rate; see mid-market rate vs bank rate.
  • Exporters and tourism gain. Westpac credits the weak NZ dollar, especially against the Australian dollar, with helping manufacturing recover. The BusinessNZ manufacturing index rose to 56.5 in September. Westpac also links it to tourist arrivals from Australia.
  • Imports cost more. Westpac now forecasts annual CPI inflation of 4.3% at the end of 2026. Higher global energy prices are the main reason, it says, and the low NZ dollar adds to them.

Will the NZ dollar get stronger?

All four NZ banks we track forecast a higher NZD/USD by the end of 2027. These are their published forecasts, not ours:

ANZ's forecasts were finalised before the RBNZ's 28 October decision.

For the end of 2026, Westpac calls a recovery to 0.58 plausible and names three things that could drive it: growing signs that New Zealand's economy is recovering, a weaker US dollar as markets price fewer Fed hikes, and renewed interest in "de-dollarisation", where investors shift money away from the US dollar. Bank forecasts are often wrong and change with each new note. See the NZD/USD forecast or every bank forecast.

Why is the NZ dollar so weak against the Australian dollar?

NZD/AUD touched 0.8004 in the week to 19 October 2026, a 13-year low, Westpac reported. It bounced to 0.8150 after softer Australian jobs data. Westpac says a rebound to about 0.83 is plausible if New Zealand's economic recovery looks more convincing over the following months. On 11 Nov 2026 the ECB reference rate was 0.8140.

Why is the NZ dollar dropping so much?

Against the US dollar, the latest drop came from the US side. Westpac's 19 Oct 2026 note put it down to US inflation data that came in higher than expected, which lifted the US dollar and took NZD/USD to 0.5565, its lowest level in 18 months, before a recovery to 0.5675. Against the Australian dollar it touched a 13-year low of 0.8004 in the same month. In ECB data, the past year's low for NZD/USD was 0.5543 on 6 Nov 2026.

Will the NZ dollar go up in 2027?

All four banks we track expect it to. Their December 2027 forecasts for NZD/USD are 0.59 (BNZ, 9 Nov 2026), 0.64 (Westpac, 19 Oct 2026), 0.59 (ASB, October 2026) and 0.60 (ANZ, 18 Sep 2026), against 0.5584 on 11 Nov 2026. Bank forecasts are often wrong and change with each new note.

Is a weak NZ dollar good or bad for New Zealand?

Both. Westpac credits the low dollar with helping manufacturers and bringing in tourists from Australia. It also makes imports dearer: Westpac says the weak NZ dollar has added to the rise in fuel-driven inflation. For anyone sending money overseas, each NZ dollar buys less.
