Company seal maker for New Zealand

The Companies Act 1993 made the common seal optional in New Zealand, so most companies formed since have never had one, though some keep a seal for share certificates.

Open the stamp maker

New Zealand removed the requirement early, in the 1993 Act, and the habit went with it faster than in most comparable jurisdictions. A New Zealand company executes documents by the signatures of directors, and many companies have genuinely never owned a seal.

What a company stamp in New Zealand usually carries

The company name exactly as registered with the Companies Office.
The NZBN, the New Zealand Business Number, or the company number.
Sometimes the year of incorporation.
On a traditional seal, the words "Common Seal" around the ring.

Why make it digitally

Share certificates are the main place a seal is still applied by convention.
Companies trading into Asia and the Pacific are asked for a stamp their own law does not require.
A digital seal survives being emailed where an embossed one does not scan.

Questions

Does a New Zealand company need a common seal?

No. The Companies Act 1993 made it optional, and documents are executed by director signature. Check the constitution, which may still provide for one.

What is an NZBN?

The New Zealand Business Number, a unique identifier for a business entity. It is not required on a seal, but it is the identifier counterparties look up.

Why keep one?

Mostly convention on share certificates, and for counterparties in markets where a stamp is still expected.
