Fill or Wait forecasts New Zealand's national average pump prices for Petrol 91, Petrol 95 and diesel, for next week and the week after. The website, the Android app and the iPhone app all show the same forecast.

Reading the forecast
- Fill soon. Prices are expected to rise, so filling up soon could save you money.
- Wait. Prices are expected to fall, so consider waiting a little longer.
- Fill anytime. Prices look stable for now, so fill up whenever suits you.
- Not available. Some of the data the forecast needs was missing today, so no call was made. This is usually back to normal within a day.
The amount is how much the average price for the week is expected to change, in cents per litre. It is a national average, so a single station can be higher or lower. The confidence beside it says how often similar past calls turned out right.
Why the call has not changed
The forecast updates once a day. Fuel prices often move slowly, so the same call can last several days. Each call is about a whole week's average price, so a rise that lands any day next week still counts.
Less reliable today
This warning appears when some of the data behind the forecast is late, or the forecast itself has not updated for a while. Treat the amount as a rough guide until the warning goes away.
The apps
The Android app is on Google Play. Both apps open on the fuel you last picked and keep the latest forecast, so they still show it when you are offline. Pull down on the forecast to check for a newer one.
If an app says "Couldn't load today's forecast", check your connection and try again. If it asks you to update, install the latest version from your app store.
Home screen widgets
Each app has two widgets. One fuel shows next week's forecast for a fuel you choose, and All fuels shows it for every fuel. The date in the corner tells you which day's forecast you are looking at.
- iPhone. Touch and hold an empty part of your home screen, tap Edit, then Add Widget, and search for Fill or Wait. To change the fuel on a One fuel widget, touch and hold it and tap Edit Widget.
- Android. Touch and hold an empty part of your home screen, tap Widgets, and find Fill or Wait. You choose the fuel for a One fuel widget when you add it.
Widgets check for a new forecast about every four hours. Your phone decides exactly when, so a widget can briefly show the day before. Opening the app updates it straight away.
Notifications
Tap Notify me on a fuel's card, or turn the fuel on under Notifications in the app's Settings. You will get an alert when that fuel's forecast for next week changes. The first time, your phone asks whether Fill or Wait may send notifications.
On iPhone, alerts can arrive late, so open the app to see the latest forecast. You may also get an alert when a forecast becomes available again after a day without one. If alerts stop, check that notifications for Fill or Wait are allowed in your iPhone's Settings.
Your data
Fill or Wait has no accounts and collects nothing that identifies you. The privacy page explains what each app keeps on your phone and how to delete it.
