New Zealand 2026 election: What National's policies could mean for your rates and water bills

The key distinction for your household is that a cap on council rates is not necessarily a cap on your total council-related costs. National's proposed rates controls could make ordinary rates increases more predictable, but water charges are treated separately, and councils would still have important decisions to make about spending and infrastructure.

For a household with a mortgage, school-age children and two incomes already committed to essentials, it's worth looking at three things separately: what you pay in rates, what you pay for water, and whether the combined cost is likely to become more manageable.

The 2026 general election is scheduled for 7 November 2026. The following explains National's documented policy direction and what it could mean for homeowners, based on information available as of 26 October 2026. sciencemediacentre.co.nz, beehive.govt.nz

1. What National proposes to change about council rates

National's government has introduced a rates-capping proposal intended to limit annual increases in council rates.

Under the proposed system:

• Annual rates increases would generally have to fall within a 2%–4% target range.
• An independent regulatory process would oversee compliance.
• Exceptions could be available in particular circumstances, such as natural disasters or other exceptional financial pressures.
• The intended implementation date is 2029.

The Local Government (Rates Capping) Amendment Bill passed its first reading in Parliament in September 2026. That means the proposal has advanced through Parliament, but you should not treat it as an unconditional guarantee that your rates will rise by no more than 4% every year. www3.parliament.nz, beehive.govt.nz, beehive.govt.nz, undecided.nz

What that could mean for your household

Imagine your annual council rates are $4,000. This is an illustration, not an estimate of your actual bill.

Annual increase	Extra cost per year	Extra cost per week
2%	$80	$1.54
4%	$160	$3.08
7%	$280	$5.38
10%	$400	$7.69

At a 4% increase, your rates would rise from $4,000 to $4,160.

If they would otherwise have risen by 7%, the proposed cap could mean $120 less in additional annual rates, assuming the cap applies as expected and no exception changes the outcome.

For a household with little money left after mortgage payments, groceries, power and other essentials, that difference could help. But it is important to distinguish slowing the increase in a bill from reducing the bill itself.

A cap also does not automatically mean that your rates will rise by only 2%–4% in every year. The final rules, permitted exceptions and how the system applies to individual councils matter.

2. What National's policies could mean for water costs

This is the most important qualification to the rates cap.

National's water policy, known as Local Water Done Well, keeps water assets in public ownership and gives councils flexibility over how water services are delivered. It also requires water services to be financially sustainable, with stronger regulatory oversight. The framework is established in legislation passed in 2025. mcert.govt.nz, assets.national.org.nz

Why water bills could still rise

The proposed rates cap excludes charges for drinking water, wastewater and stormwater. Those costs are dealt with separately from ordinary council rates. mcert.govt.nz, www3.parliament.nz

That matters because councils need to maintain and upgrade ageing pipes, meet water-quality requirements and provide infrastructure for growing communities.

Under the water reforms, councils must establish financially sustainable ways of delivering these services. Depending on the local arrangements, that can involve borrowing for infrastructure, changing how services are organised, or adjusting water charges.

The government's framework does not guarantee that these changes will make water cheaper for households. mcert.govt.nz, dia.govt.nz

How this could affect your budget

Consider a hypothetical household facing the following annual changes:

Household cost	Annual change
Ordinary council rates	+$160
Water charges	+$200
Combined additional cost	+$360
Equivalent weekly increase	+$6.92

These figures are illustrative, not a forecast of your council's charges.

Even if ordinary rates increased by only 4%, a separate increase in water charges could leave your household paying more overall.

The other important point is that a water charge may appear on a separate invoice or within your council rates, depending on your local arrangements. You need to consider both to understand your actual housing-related costs.

For a national overview, the Ministry for Cities, Environment, Regions and Transport explains the rules under Local Water Done Well.

3. What would remain a council decision?

National can change the rules councils operate under, but it does not automatically decide every aspect of your local bill.

The proposed rates cap is designed to constrain how quickly councils can increase their rates revenue. Councils would continue to make decisions about local services, infrastructure investment and spending priorities. mcert.govt.nz, mcert.govt.nz

Here is the practical distinction.

Issue	National government can influence or set	What remains local
Ordinary rates	The proposed annual increase range and rules for exceptions	How rates are allocated among properties and rating categories, within the applicable rules
Water charges	The legislative framework, regulatory requirements and economic oversight	The local service-delivery arrangements and associated charging decisions, within the law
Water infrastructure	National standards and regulatory requirements	Local investment plans, project priorities and delivery arrangements
Rubbish collection, parks and pools	The broader legislative framework and limits on rates revenue	Service levels, spending choices and local priorities
Growth and development	National planning rules and infrastructure-funding frameworks	Local planning and implementation decisions within those frameworks

These distinctions follow the government's description of the proposed rates-capping system and the water-services framework. mcert.govt.nz, mcert.govt.nz

Could a council still raise your individual rates by more than 4%?

Potentially, yes.

The proposed cap applies to a council's average rates revenue per rating unit, rather than guaranteeing a maximum increase for every property.

Your individual bill can change by a different percentage because of property valuations, targeted rates, the way costs are allocated, and local rating decisions. Approved exemptions can also affect the overall outcome. mcert.govt.nz

This means that even if National's proposal takes effect as intended, you should not assume that your particular rates bill will be limited to a 4% increase every year.

4. What about other parties in the 2026 election?

If you are considering National's approach, it is also useful to distinguish its proposed rates cap from the alternatives other parties might pursue.

I would compare parties on the actual mechanisms they propose, rather than assume that a promise to reduce living costs necessarily means lower rates or water bills.

For each party, look for answers to these questions:

• Would it cap council rates, and if so, at what level?
• Would the cap include water charges, or would those remain separate?
• Would it provide central-government funding for water infrastructure, or leave more of the cost to councils and their customers?
• Would it change how councils can borrow, collect revenue or charge for local services?
• When would the policy take effect?

National's published policy provides a specific 2%–4% target range for ordinary rates increases, with implementation planned for 2029. Its water framework focuses on financially sustainable services under Local Water Done Well. Those are two distinct policies, with different implications for household bills. national.org.nz, mcert.govt.nz

5. What should you check before voting?

Given that your household has limited room in its budget, I would focus on the likely effect on your combined annual housing and council costs, rather than the headline rates percentage alone.

Here is a practical checklist.

A. Look at your council's latest annual rates bill

Identify:

• Your ordinary general rates.
• Any targeted rates or separate council charges.
• Water supply, wastewater and stormwater charges, wherever they appear.

B. Check the council's water-services plans

Look for planned infrastructure upgrades, forecast operating costs, proposed charging changes and the arrangements for delivering water services.

The government's Water Services Delivery Plans information explains how councils plan to fund and deliver water services.

C. Ask what happens between now and 2029

National's proposed rates cap is not intended to take effect until 2029. It therefore does not, by itself, protect your household against rates increases before then, nor does it guarantee a particular water charge.

Check the rates and water forecasts for the intervening years, not just the proposed long-term cap. national.org.nz, www3.parliament.nz

D. Look beyond the percentage increase

A council can have a relatively modest percentage increase but still impose a substantial dollar cost on a household. Conversely, a higher percentage increase on a small charge may have a smaller effect.

For your family, the important measure is how many additional dollars you would have to find each week.

---

Bottom line

National's proposal could make ordinary council rates increases more predictable by introducing a 2%–4% target range, subject to the final legislation and exceptions. But water charges are excluded from that cap, and water infrastructure still has to be paid for.

Councils would retain important decisions about service levels, infrastructure investment and local charging arrangements within national rules.

The question to put to any party is therefore:

Will your policies reduce the combined amount our household has to pay for ordinary rates and water services, and by how much each year?

That is a more revealing test than asking whether a party will simply cap rates.

Before relying on any particular promise, check whether it applies to your entire bill, when it begins, and how it will be funded. Those details determine whether a policy offers meaningful relief to a household already stretched by mortgage repayments and everyday costs.
