We are Tennant.

We are a specialist Retail Tenant Advisory practice based in Auckland, New Zealand, founded on a single principle: retailers deserve the same level of strategic sophistication that landlords deploy every day.

We sit 100% on the side of the retailer, optimising every dimension of performance – from securing the right sites to cutting the hidden transaction costs that erode margins.

Tenant-First Advocacy

We sit 100% on the side of the retailer, providing conflict-free representation to ensure tenants have the same strategic sophistication as landlords.

Having spent over a decade on the landlord side of the table, we use our knowledge of their playbook to become our clients’ greatest strategic asset.

Action-Oriented Rigour

We cut through the fluff with a focus on measurable P&L outcomes, securing best-in-market terms and identifying hidden savings that grow your bottom line.

Sophisticated Tenacity

We combine premium, award-winning property credentials with the relentless drive needed to fight for the outcomes our clients deserve.

our values.
