One NZ sells two roaming families. Pay monthly daily roaming is charged per day of use and runs on the allowance already in your home plan. It covers more than 165 destinations, among them Australia, the USA, the UK, Canada, Japan, Thailand, Indonesia (Bali), Singapore, Malaysia, Hong Kong, South Korea, Dubai (UAE), Vietnam, Turkey, Germany, France, Italy, Spain, the Netherlands, Greece, Portugal, Ireland and Switzerland. It is available on all current Pay Monthly plans except Mobile Broadband. Weekly Prepay Roaming is a Prepay bundle lasting 7 days with 1 GB of data and 100 call minutes.
Daily Roaming needs no set up. Switch the phone on and roaming works when you land. The daily charge applies only on days you make or answer a call, including to voicemail, send a TXT or use data. Days are counted by NZ calendar day. Receiving TXTs is free and does not trigger the charge. The daily fee is charged for up to 90 consecutive days. On endless data plans, data continues at up to 1.2 Mbps while roaming once Max Speed Data is used. Prepay Roaming bundles cover more than 70 destinations and run for their 7 days.
Travellers who want to keep their One NZ number for calls, texts and bank codes can leave the home SIM in the phone and add a Slashtel prepaid data-only travel eSIM, sold for 190+ countries. The eSIM carries mobile data and connects to local networks, with network selection automatic. It is installed by QR code before the trip and switched on when you land. A data-only eSIM has no phone number, so calls and texts stay on the home SIM or go over internet apps. WiFi Calling overseas does not need roaming turned on, and its minutes and TXTs come out of the plan allowance.
The table above lists each One NZ pack against live data eSIM prices for the same trip, destination by destination. For destinations where the eSIM costs less, pairing the two covers data on the eSIM while the One NZ SIM stays reachable, without triggering the daily charge on days you only use data on the eSIM. See roaming from New Zealand for the other New Zealand operators.
