A comparison between an affidavit and a statutory declaration document in New Zealand.

In New Zealand, an affidavit is a written statement of facts you swear or affirm to be true before an authorised person, used as evidence in court. A statutory declaration is a similar formal statement you declare to be true, but it's primarily for administrative purposes with government agencies or banks. The key difference is their legal context and governing rules.

What is an Affidavit in New Zealand?

An affidavit is a formal written statement of facts. You swear an oath or make an affirmation that its contents are true. Its core purpose is to serve as evidence in court proceedings and other formal legal disputes.

Swearing or affirming an affidavit is a serious legal act. Making a false statement in an affidavit can lead to charges of perjury, which is a criminal offence.

What is a Statutory Declaration in New Zealand?

A statutory declaration is a written statement you formally declare to be true before an authorised witness. It is not intended for use as court evidence. Instead, it is used to verify information for administrative purposes.

Common uses include confirming your identity or residency for a government agency, declaring the loss of a passport or driver's licence, or verifying personal details for a bank or employer.

Key Differences: Affidavit vs Statutory Declaration

Understanding the legal meaning of an affidavit and how it differs from a statutory declaration is crucial for using the correct document.

AspectAffidavitStatutory Declaration
Governing LawPrimarily the Oaths and Declarations Act 1957, alongside court rules and the Evidence Act 2006.The Oaths and Declarations Act 1957.
Primary ContextCourt proceedings and formal legal disputes.Administrative processes with government, banks, employers, etc.
Standard WordingYou 'swear' or 'affirm' the contents are true.You 'solemnly and sincerely declare' the contents are true.
Consequences for False StatementsPerjury, a criminal offence.Making a false declaration, a criminal offence.

The lists of authorised witnesses (e.g., Justices of the Peace, lawyers, court officials) are very similar for both documents, though specific requirements can vary.

When Do You Need an Affidavit?

You need an affidavit when you must provide formal, sworn evidence for a legal process. Specific scenarios include:

  • Family Court proceedings, such as affidavits in support of parenting or relationship property applications.
  • Providing written evidence for a civil or criminal court case.
  • Certain immigration tribunal or deportation matters.
  • Whenever a lawyer or a court specifically requests a sworn statement.

When Do You Need a Statutory Declaration?

You need a statutory declaration for official matters that require a formal declaration of truth outside of court. Common situations include:

  • Applying for a passport or confirming a name change with the Department of Internal Affairs.
  • Verifying details for banks or other financial institutions.
  • Declaring the loss or theft of a driver's licence, passport, or other document.
  • Confirming eligibility for a government benefit, pension, or scholarship.
  • Providing statements required by an employer or a professional licensing body.

How to Swear an Affidavit or Sign a Statutory Declaration

The process for finalising both documents is similar and has strict requirements.

  1. Find an authorised witness. This is typically a Justice of the Peace, a lawyer, a court registrar, or a notary public.
  2. Be physically present. You must sign the document in the physical presence of the witness.
  3. Undertake the formal act. For an affidavit, you will either swear an oath on a religious text or affirm the truth. For a statutory declaration, you will solemnly declare the contents are true.
  4. The witness completes it. The witness will then sign, date, and often stamp the document, adding their official title and details.

What is an Affidavit of Support?

An Affidavit of Support is a specific type of affidavit used in New Zealand immigration. Its purpose is for a sponsor to declare they will provide financial support to a visa applicant, such as for a partnership visa.

It differs from a general affidavit in its specific content, focusing on the sponsor's financial commitment and relationship to the applicant. It is a key piece of evidence for many visa applications.

Common Mistakes to Avoid

To ensure your document is valid and accepted, avoid these common errors:

  • Using the wrong document: Do not use a statutory declaration where a court requires an affidavit.
  • Unauthorised witness: Confirm the person witnessing is authorised for that specific document type.
  • Incomplete information: Ensure the document includes your full legal name, address, and the date.
  • Including opinions: Stick to statements of fact you know to be true, not beliefs or opinions.
  • Signing in advance: Never sign the document before you are with the authorised witness.

Next Step

Now that you understand the differences, you can create the correct document for your needs. Using a professional template ensures it contains all necessary legal wording. You can start by creating an Affidavit or a Statutory Declaration.
