Pros and cons
Pros
- A debit card on the mastercard network, set up as a family account for shared household spending.
- Support runs on phone, email and chat, covering phone, email and chat.
- A named operator behind the balance in Booster Investment Management Limited, based in New Zealand.
Cons
- The currency conversion fee of 2% sits well above the 1% site median, so foreign purchases cost more.
Who it suits
- Households in NZ that want one debit card shared across family members.
- Families who want no monthly charge and support on phone, email and chat.
Who should look elsewhere
- Wise, for readers who convert currency often enough that a 2% conversion fee adds up.
- Varo Believe Secured Credit Card, if you want a secured credit card rather than a debit family card.
- Chime Card (Secured Visa Credit Card), if you want a secured Visa credit card rather than family debit spending.
Fees and currency costs
Booster Savvy charges a monthly fee of NZD 0 for the family account, so there is no recurring cost to budget for. Currency conversion is the item to watch, with a fee of 2% where the site median sits at 1% and the upper quartile mark is 2.5%. Card purchases at home are the low-cost path.
Who runs it
Booster Savvy is operated by Booster Investment Management Limited, based in New Zealand. Support runs on phone, email and chat, so customers get a phone line, an email address and live chat rather than a single route to the team. A named legal entity on the terms is useful when checking who stands behind the balance, and having several channels means a blocked phone call does not have to end the conversation.

Frequently asked questions
What does Booster Savvy cost each month?+
The monthly fee is NZD 0, so the account carries no recurring charge. The fee to watch is currency conversion, which runs at 2%. Buying in NZ on the card is the cheap path, and converting foreign currency is where a bill builds up.
Is Booster Savvy a debit card or a credit card?+
It is a debit card, so spending draws on money already in the account rather than building a balance to repay. The card runs on the mastercard network, the one most terminals and cash machines accept.
Who runs Booster Savvy?+
The account is operated by Booster Investment Management Limited, which is based in New Zealand. The company name on the terms tells you who stands behind the balance, and contact runs on phone, email and chat for questions about the card or the account.
How do I reach support?+
Support runs on phone, email and chat, so there is a phone line, an email address and live chat. A phone call suits a blocked card or a disputed payment, while email and chat work for routine questions that can wait for a written reply.
Who is Booster Savvy for?+
It is built as a family debit card, so it suits households in NZ that want one account covering several family members' everyday spending. The monthly fee of NZD 0 keeps that shared setup cheap to hold.
Is Booster Savvy any good for spending overseas?+
Less so. The currency conversion fee is 2%, above the 1% site median, so every foreign purchase costs more through conversion. Readers who convert regularly should weigh a multi-currency option such as Wise before settling on a family debit card.
How does Booster Savvy rank on cost?+
It sits at rank 1 of 419 on monthly fee, with a fee of NZD 0. The comparison flips on currency conversion, where the 2% charge runs past the 1% median across the site.
