--- title: "NZ Bill Splitter: Split Dinner With or Without Tips | AumnI tools" description: "Divide a bill in New Zealand dollars between diners, starting at no tip, and compare what 5%, 10% and 15% would add to the whole table and to each share." url: https://aumnitools.com/nz/tool/tip-and-bill-splitter category: "Lifestyle" country: "New Zealand" updated: 2026-11-08 --- # Tip and Bill Splitter Dinner in New Zealand is usually split without a tip, so this page opens at 0% and shows the plain share first. The row of buttons then adds 5%, 10% or 15% if the group wants to leave something. Everything is divided equally by head count and shown in dollars. ## New Zealand rules and figures - Even in restaurants and bars a tip is not obligatory, says Tourism New Zealand. - Good service or kindness may earn a tip, entirely at the diner's discretion. - No percentage is given by the tourism body, so the 5%, 10% and 15% buttons are only suggestions. - Service charges are not added to bills by hotels and restaurants. - Shelf prices already contain GST at 15%.

With the opening 0% the tip is nil, so each share is simply the bill divided by the count. Formula: `each = $180.00 ÷ 4 = $45.00 at 0%; with a tip, each = bill × (1 + tip% ÷ 100) ÷ 4` - Four buttons appear: 0% No tip, 5% Standard, 10% Good Service and 15% Great Service. The slider goes up to 20%. - The badge says Little or No Tip below 5%, so the opening value reads that way. - The comparison list on the Breakdown tab repeats the four buttons and shows the table total for each. - GST at 15% is already in the printed prices, and hotels and restaurants do not add service charges. - Tourism New Zealand names no percentage, so the buttons are suggestions only. ## How to use the Tip and Bill Splitter 1. **Enter the amount on the bill.** Type the total, for instance $180.00. 2. **Add the number of diners.** Raise the counter until it equals the people dividing the cost. 3. **Read the per-person figures.** Each person pays appears on the Breakdown tab. Use Copy Total to send the amount, or pick a button first if the group would like to tip. ## Example: $180.00 for 4 people, with and without a tip At the opening 0% each person pays $45.00 and the total is $180.00. At 5% the tip is $9.00, the total $189.00 and each share $47.25. At 10% each pays $49.50, and at 15% each pays $51.75, with table totals of $198.00 and $207.00. ## When to use the Tip and Bill Splitter - **Splitting the plain bill.** Leave the tip at 0% and read what each person owes. - **Adding a small thank-you.** Press 5% and see what it costs each person at the table. - **Comparing a group tip.** Check the four totals on the Breakdown tab before the group agrees. - **Dividing a shared trip fare.** Enter the fare, keep the tip at nil and share it among passengers. ## What the Tip and Bill Splitter does not do - Each person pays the same amount, whatever they ordered. - Tax cannot be entered, so any tip percentage applies to the whole bill including GST. - The tool shows shares to the cent without rounding them up, so they can differ from the total by a cent. - The tool records nothing and moves no money. - A reset returns the page to 0% and an empty bill. ## When something else is a better fit - **When you want the tip taken from the pre-GST amount**, use the [Tip Calculator](https://aumnitools.com/tool/tip-calculator.md), which has a tax box. - **When the group is sharing a shop purchase on sale**, use the [Discount Calculator](https://aumnitools.com/tool/discount-calculator.md). ## Questions about the Tip and Bill Splitter ### Why does the splitter open with no tip? Tipping is not obligatory in New Zealand, even in restaurants and bars, so a plain split is the usual outcome. ### How much does each person pay at 0%? The bill is divided by the head count. $180.00 among 4 people is $45.00 each. ### What would a tip add for the table? On $180.00, 5% adds $9.00, 10% adds $18.00 and 15% adds $27.00. ### Will the restaurant add a service charge? Not normally. With no service charge on the bill, the printed total is the amount to divide. ### Is GST extra? No. GST at 15% is included in the prices on the bill. ## Related tools - [Tip Calculator](https://aumnitools.com/tool/tip-calculator.md): Works out a tip and total from a bill, with tax handling, rounding and bill splitting - [Percentage Calculator](https://aumnitools.com/tool/percentage-calculator.md): Eight percentage questions solved from two numbers, with each step shown - [Discount Calculator](https://aumnitools.com/tool/discount-calculator.md): Stack discounts in order, add or strip tax, rank multi-buy deals and compare unit prices ## About this page Runs in your browser: what you enter is processed on this device and is not uploaded.
