About Grin

Grin Natural is a New Zealand oral-care brand creating thoughtful, sustainable alternatives that care for people and the planet. Our range combines naturally derived ingredients with innovative product design, while avoiding SLS, artificial colours and flavours, and harsh abrasives.

Role description

The Content Marketing Intern is a full-time, paid summer internship based on-site at our Rosedale office in Auckland.

Working closely with GRIN’s marketing team, you’ll help plan, produce and appear in engaging content across our social channels and international markets.

Your responsibilities will include

• Monitoring social media trends and identifying relevant opportunities for Grin
• Planning and producing short-form content for platforms such as TikTok and Instagram
• Confidently appearing in content as one of the faces of the brand
• Helping develop content calendars and campaign concepts
• Creating clear briefs for internal and external content creators
• Filming and editing social-first videos

• Assisting with product launches, creator activity and wider marketing campaigns
• Conducting basic audience, competitor and trend research
• Collaborating with different teams to gather accurate product and brand information
• Organising content, references and campaign assets
• Reviewing content performance and identifying opportunities for improvement

You’ll be encouraged to contribute your own creative ideas, experiment with different formats and help us produce content that feels entertaining, relevant and distinctly Grin.
