Launch & grow a successful side hustle

If you’re thinking about starting a side hustle but feeling a little overwhelmed, we’re here to help.

Five tips for a happy hustle

Laying solid groundwork is key when starting a side hustle. With so much advice out there, and self-proclaimed gurus, it’s easy to feel overwhelmed. By focusing on the fundamentals, you can build something sustainable and rewarding.

The good news is that building your own small business doesn’t have to be complicated. Just ask Joanna Greaves, General Manager of Business Banking at Kiwibank and an avid side hustler herself.

Joanna knows firsthand what separates successful side hustles from those that fail to flourish. Her family runs a small egg business in Manawatu – a classic Kiwi side hustle rooted in community, hard work, and supporting local.

Here are Joanna's top five tips to help you launch and grow a successful side hustle.

    Start with your why

    For Joanna, her side hustle is about so much more than just the extra income; it's a way to teach her kids valuable life lessons and build connections with the local community.

    At the beginning of your journey, ask yourself: why do you want a side hustle? Is it about extra income, learning new skills, or turning a passion into something bigger? Clarifying your purpose will boost your energy and motivation when things get tough.

    Know your numbers

    You don’t need to be a money maestro to get started, but you do need a manageable plan. Work out your startup costs, expected income, and how long you can keep things afloat before your side hustle stands on its own two feet.

    It’s okay if numbers aren’t your thing, there’s a lot of potential support out there – mentors, business networks, and free small business courses (many NZQA-accredited) that can help you get the basics sorted. Try searching online for ‘free small business course NZ’ and you’ll find plenty of options.

    Tap into the Kiwi ecosystem

    There's plenty of places to look for help with your hustle. New Zealand has a thriving ecosystem for side hustlers and small business owners. Joanna recommends joining local business networks, connecting with mentors, and taking advantage of innovation hubs like the Ministry of Awesome, and programmes like Startup Aotearoa.

    Reach out, ask questions, and connect with experienced side hustlers who’ve navigated the same path.

    Separate your finances early

    Joanna advises that one of the smartest moves you can make is to set up a separate bank account for your side hustle early. Even if you’re just starting out, keeping your business and personal finances apart should make everything easier – tracking income, claiming expenses, and showing you’re serious to customers and lenders.

    It’s quick to set up, and it helps you build good habits from day one. An added bonus is no more hunting for receipts or sorting through your personal account at tax time.

    Protect your wellness — it’s a business asset

    Juggling a side hustle with work and family can be tough. If you’re not careful, it’s easy to burn out. Joanna emphasises the importance of remembering that your wellbeing is just as important as your bottom line.

    Set boundaries, ask for help, and make time to rest and recharge. Building your support network and looking after yourself will help you go further and, more importantly, enjoy the journey.

Your next step

Starting a side hustle is about more than making extra cash. It’s about learning, connecting, and building something you’re proud of. As we’ve learnt from Joanna, with the right support and a clear plan, you can make your side hustle a success that works for you.

Quick recap:

  • Define your purpose
  • Understand your finances
  • Tap into local support
  • Separate your business finances
  • Prioritise your wellbeing
It's a brilliant contrast to my day job. It's grounding, practical, and serves as a strong reminder of the challenges and joys that small business owners face every day.
