In-House Marketing Team or Agency?

How to Make Your Business More Nimble

For growing businesses in New Zealand and Australia doing between $2 million and $20 million in revenue, an embedded marketing partner can work alongside your existing team or operate as your full marketing function — giving you senior strategy and execution power without the cost of building an entire department.

The way businesses build their marketing capability is shifting. Five years ago, the playbook was straightforward: hire a marketing manager, maybe add a coordinator, and figure the rest out as you go. That worked when the pace of change was manageable and digital was one channel among many. But the landscape across New Zealand and Australia has moved on. Channels multiply faster than teams can learn them. AI is reshaping how customers find businesses. And the companies that are growing fastest are the ones building marketing functions that can flex, adapt, and move without being weighed down by traditional structures.

This is not about whether in-house teams are good or bad. A strong internal marketing person who knows your brand, your customers, and your culture is incredibly valuable. The question is whether that person, or even a small team, can realistically cover the full breadth of what modern marketing demands. Strategy, brand, digital, content, social, campaigns, analytics, SEO, paid media. The list keeps growing, and the smartest businesses are getting nimble about how they resource it.

Why Is the Old Model Under Pressure?

Marketing used to be a department that ran campaigns. Now it is the engine that drives how customers discover, evaluate, and choose your business. Across Australasia, buyer behaviour has fundamentally changed. People research online before they ever pick up the phone. AI tools are answering their questions directly. Social proof and content carry more weight than a slick brochure. That means your marketing function needs to operate across more channels, at a higher standard, and with more strategic depth than ever before.

The challenge for growing businesses is that this breadth of capability is hard to build internally without significant investment. A marketing manager in New Zealand or Australia will cost somewhere between $100,000 and $140,000 per year. Add a content creator, a digital specialist, and a designer, and you are looking at $350,000 to $500,000 annually in salaries alone, before tools, software, or ad spend. That investment makes sense for some businesses. But for many in the $2 million to $20 million range, it is a big commitment, especially when the skills you need today may not be the same skills you need in twelve months.

What Does a More Nimble Marketing Setup Look Like?

The businesses we work with across New Zealand and Australia are increasingly moving toward a flexible model. Some have a strong marketing lead in-house who handles brand guardianship, internal stakeholder management, and day-to-day coordination. They then bring in an embedded agency to provide the strategic depth, creative firepower, and specialist execution that would take years and significant budget to build internally. Others do not have anyone in-house yet and use the embedded model as their full marketing function until the business reaches a scale where internal hires make sense.

It is the difference between having a supplier and having a partner who is genuinely invested in your growth.

The embedded approach is different from the traditional agency relationship. Instead of sitting outside the business, waiting for briefs and delivering campaigns at arm’s length, an embedded team plugs directly into how you operate. They join your planning sessions, understand your revenue targets, and build strategy that is connected to what is actually happening in the business week to week.

What makes this nimble is the ability to flex. When you are launching a new product or entering a new market, you can scale up capability immediately without going through a three-month recruitment process. When things are quieter, you are not carrying salary overhead for a team that is underutilised. For businesses operating across both sides of the Tasman, this flexibility is particularly valuable because you can access a team that understands both markets without doubling your headcount.

Where Does an In-House Team Add the Most Value?

In-house marketing people are at their best when they are deeply connected to the brand, the culture, and the internal dynamics of the business. Nobody understands the nuances of your customer conversations, your leadership team’s vision, or the internal politics of getting things approved better than someone who lives it every day. A good internal marketing person is your brand’s voice and your team’s translator, turning business objectives into briefs that actually make sense.

Where in-house teams often struggle is when they are expected to be everything to everyone. One person cannot realistically be a strategist, a copywriter, a designer, a digital ads expert, an SEO specialist, and a data analyst. Yet that is what many growing businesses ask of their marketing hire, sometimes without even realising it. The result is a capable person spread too thin, doing a lot of things adequately but none of them with the depth that drives real results. That is not a reflection of the person. It is a structural problem, and it is one that an embedded partner is specifically designed to solve.

How Do You Decide What Is Right for Your Business?

Start with an honest assessment of where you are today and where you need to be in twelve months. If you already have a marketing person in-house, think about what they are great at and where the gaps are. Chances are, the gaps are in specialist execution areas like digital campaigns, SEO, content strategy, or creative production. An embedded partner can fill those gaps without you needing to hire three more people. Your in-house person gets to focus on what they do best, and they get a team of specialists to collaborate with rather than trying to do it all alone.

If you do not have anyone in marketing yet, consider whether your first move should be a hire or a partnership. Hiring gives you a dedicated person but a narrow skill set. An embedded agency gives you a full team from day one, which means you can start building momentum immediately while you figure out what an eventual in-house role should look like. Many of our clients across Australasia started with us as their full marketing function and later hired internally once they had a clearer picture of what they needed on the ground.

Budget matters too. If you have the capacity to invest $350,000 or more per year in marketing salaries and you are prepared for the recruitment timeline, building in-house could be the right call. But if your budget is better suited to $5,000 to $25,000 per month and you want senior strategic thinking alongside hands-on execution, an embedded partner gives you significantly more capability per dollar. The maths tends to be particularly compelling for businesses in the growth stage where every dollar needs to work hard.

The Bottom Line

The question is no longer in-house versus agency. The world has moved past that binary. The real question is how to build a marketing function that is nimble enough to keep up with a market that will not slow down and deep enough to deliver results that actually move the needle. Across New Zealand and Australia, the businesses getting this right are the ones that think about marketing capability, not just marketing headcount. They are combining internal knowledge with external expertise to create something more powerful than either could deliver alone.
