Types of cover
Booster and top-up benefits
Booster and supplementary benefits are add-on layers that lift what you receive in the early months, or that fit deliberately around ACC. Used well, they close real gaps for less money.
Last reviewed 4 September 2026 · Written and checked by the Best Life Insurance editorial team · How we get paid
In short
- A booster benefit pays an additional amount for a limited period, usually the first months of a claim.
- Supplementary benefits sit above a base benefit and can lift total cover beyond the standard percentage.
- ACC top-up structures are priced on the assumption ACC pays first, so they cost less and offset cleanly.
- These layers are subject to their own limits and expiry provisions, and can be shorter than the main benefit period.
- They are a way to buy a higher benefit for the period that hurts most, without paying for it to age 65.
- Availability and naming differ by insurer, so ask about the concept rather than a brand name.
What this is, plainly
Standard income protection insures one monthly benefit for one benefit period. Real financial stress does not work that way — the first six months of a serious illness are usually far more expensive than the second year, because that is when treatment is intensive, a partner takes time off, and the household has not yet adjusted its spending.
Booster benefits address that shape. They pay an additional monthly amount for a defined early period, commonly six or twelve months, on top of the base benefit. Because the extra cover only runs for a short window, it costs far less than lifting the base benefit permanently.
Supplementary benefits do something different: they allow total cover above the base percentage limit, usually structured so that the additional layer is subject to different offset or evidence conditions. And ACC top-up structures are built on the assumption that ACC pays first for accidents, which lets the insurer price the cover on the illness risk it is genuinely carrying.
When these structures help
- A household with high fixed costs in the first year of a claim — private treatment, travel, childcare — but the ability to adjust afterwards.
- Someone whose employer sick leave runs out at a known point, where a booster can bridge the step down.
- A self-employed person who wants meaningful cover but cannot fund a high benefit to age 65.
- Anyone whose occupation makes accident-related disability likely and who wants to avoid paying for cover ACC will offset anyway.
- A situation where the insurer’s base percentage cap leaves a real shortfall against essential outgoings.
The same principle applies in reverse. If money is tight, these layers are the first thing to remove, because dropping a booster preserves the base benefit and the benefit period — which is the part that protects against the catastrophic claim.
Not sure what cover you actually need?
That is the question an adviser is there to answer. Tell us your situation and a licensed New Zealand adviser will compare the market and come back with a written recommendation — including where you can cut cover you do not need.

What to watch for
These are the details that decide whether the cover does what you expected. Read them before you compare on price.
- How long the booster runs and whether the period restarts after a return to work.
- Whether the supplementary layer is subject to different offset rules than the base benefit.
- Whether financial evidence is required at claim for the additional layers.
- The expiry age of each layer, which may be earlier than the base cover.
- Whether the total across all layers still respects the insurer’s financial underwriting limits.
- Whether an ACC top-up structure genuinely pays for illness at the full rate.
Where an adviser makes a difference
Every New Zealand insurer writes income protection in new zealand to its own wording, and the words are where the money is. Two policies that look identical on price can pay very differently when it matters. Closing that gap is the entire job of an adviser.
- Naming is inconsistent across insurers — the same concept appears under several product names, so the comparison has to be structural.
- An adviser can model a base plus booster against a single higher benefit and show the cost difference over the full term.
- For occupations with high accident risk, an ACC top-up structure can be significantly better value than standard cover that will be offset anyway.
- Where affordability changes, removing a layer is a cleaner adjustment than reducing the whole benefit.
There are three ways to buy life cover in New Zealand, and they are not equivalent. You can buy direct from one insurer, which means you see one product range and one underwriting appetite. You can buy through your bank, which usually means a single insurer’s product sold under the bank’s brand, often with narrower definitions. Or you can go through an adviser, who quotes several insurers at once and is required to put your interests first.
The premium you pay is the same either way. Insurers build adviser commission into their pricing whether or not an adviser is involved, so going direct does not get you a discount — it just removes the person whose job is to argue your corner at application and at claim time.
- An adviser can see which insurer is currently taking your health history on standard terms, and which one will load or exclude it.
- An adviser can structure cover across two insurers if that produces a better outcome than putting everything with one.
- An adviser handles the underwriting back-and-forth, and is the person who chases the claim when a family is least able to.
- An adviser has to document why the recommendation suits you, which is a written record you can hold them to.

Frequently asked questions
What is a booster benefit on income protection?
An additional monthly amount paid for a limited early period of a claim — often six or twelve months — on top of the base benefit. Because it runs for a short window it costs far less than permanently increasing the benefit.
What is an ACC top-up income protection policy?
Cover priced on the basis that ACC pays first for accident-related disability, with the insurer’s benefit designed to sit above it. It costs less than standard cover because the insurer is mainly carrying the illness risk, which ACC does not cover at all.
Can supplementary cover take me above 75% of income?
Sometimes, depending on the insurer and the structure. Supplementary layers are often subject to different offset or evidence conditions, which is what allows the total to exceed the standard base cap. Financial underwriting limits still apply across all your cover.
Should I add a booster or increase my base benefit?
It depends on where the pressure falls. If your household costs spike in the first year and then adjust, a booster is efficient. If the shortfall is permanent, increasing the base benefit is the honest fix even though it costs more.
What should I drop first if I cannot afford my premium?
Usually the supplementary layers, then the booster, before touching the base benefit or the benefit period. Those layers improve a claim; the base benefit and the benefit period are what protect against the claim that never ends.
