Social Media Advertising

Ads that don’t just spend. They perform.

Boosting a post isn’t a strategy. Most social ad budgets don’t fail because the platform is broken. They fail because nobody decided what the ad was for, who it was talking to, or how anyone would know if it worked. That’s the bit we fix. We’re a paid social team based in Wellington, working with brands from Wellington to Auckland. Strategy, creative, tracking and optimisation all sit under one roof. One plan, one team, no handoffs where the good ideas go to die.

OUR APPROACH

How we build social ads that perform

Built for each platform, not copy-pasted across them

A Reel isn’t a TikTok. A LinkedIn ad isn’t a Facebook ad. We make creative for how people actually use each feed, so it lands like it belongs there.

Audience first, always

Before we write a hook, we work out what your customer cares about, what they’re sick of hearing, and what would make them stop. Often the best message comes straight from the customer’s own words.

Test on purpose, not by accident

Every campaign carries deliberate tests: hook against hook, long copy against short, founder against product. Set up so the answer actually means something.

Optimise like we mean it

We cut what’s not working early and move budget into what is. Weekly, not quarterly. And we’ll tell you when the cheapest lead isn’t the best one.

What We Do

Meta and Instagram: Full-funnel campaigns across Feed, Reels and Stories.

TikTok: Native, sound-on video and Spark Ads built for the For You page.

LinkedIn: Sponsored Content, Document Ads and Lead Gen Forms for decision-makers.

YouTube and paid social creative: Demand-building video with UGC, statics and carousels.

Why It Works

Paid Social Strategy, Testing and Optimisation: Every campaign starts with a business number: bookings, sales, enquiries or enrolments. Then we build the funnel to hit it, including lead magnets, landing pages and nurture where they help. Structured creative and audience tests run from day one, and budget follows the results.

The outcomes

Paid Social Measurement and Reporting: Pretty creative with no tracking is a guess. We set up Meta Pixel and Conversions API, TikTok Pixel, LinkedIn Insight Tag and GA4 properly, so spend links back to revenue. Reporting tells you what happened, why, and what we’re doing next. In plain English.

Social ads designed to generate demand, leads and revenue.

Creative made for the feed it appears in, not adapted as an afterthought.

Deliberate testing that gives the team usable answers.

Clear tracking from paid social spend back to the business number that matters.

Campaigns run by a Meta Business Partner, not a guess.

Paid social FAQs

How much should I spend on social media advertising in New Zealand?

It depends on your goals, market size and where your customers are. Pushing more budget into a small area just buys repetition, not results. We’ll recommend a test budget big enough to learn from, then scale what works.

How long before social ads get results?

It depends on where you’re starting from. An established ad account, a healthy budget, plenty of creative, and a strong offer and message all speed things up. Either way, we expect to see early signals within the first week, and we’ll tell you what they mean.

Why is testing so important?

Because nobody knows for sure what will work until real people see it. When you launch a new product, service or message, testing in rounds shows us whether there’s product-market fit, and which messages and hooks actually land. We test everything and let the data speak.

How is Sea different to other agencies?

Four things: we test everything; creative strategy starts with your audience; we take you on the journey with clear reporting; and we make native-first ads that feel like content, not interruptions.

Should I advertise on Meta or TikTok?

Most New Zealand brands start on Meta for its reach and targeting. TikTok is often cheaper for attention and strong for younger audiences. We usually test both and let the numbers decide.

Do you make the ad creative?

Yes. Strategy, scripting, direction, editing and copy all happen in-house, so the creative and the media plan are built together.

Do I own my ad accounts and data?

Always. Your ad accounts, pixels and data stay in your name. We work inside them.

What’s the difference between social media advertising and social media management?

Advertising is paid: campaigns with budgets, targeting and measurable outcomes. Management is organic: content, posting and community. Plenty of clients use both.
