Gerrard got her second job in advertising, temping as an account executive at Saatchi & Saatchi Auckland, when she was still at university. She got her first job when she was eight, cast as the lead in a commercial for Sammies, a cheese-filled biscuit sold south of the equator. Gerrard hated the biscuits but fell in love with advertising. After four years at Saatchi & Saatchi Auckland, she moved to London and freelanced before landing a job at Albion.

Gerrard says: "In New Zealand, agencies are a lot smaller and so they do everything. But, in the UK, they tend to specialise. What I enjoy about Albion is that it’s more like the agencies back home."
