APA reference list , Ko tā APA rārangi tohutoro

Learn how to format all your resources in APA reference lists.

Overview

The reference list appears at the end of the assignment under the heading References. It lists detailed information about each source cited in the assignment. List every source mentioned in an in-text citation in the reference list. Don't list a source if there isn't an in-text citation.

Each entry has 4 elements:

  • Name of the author
  • Date of publication
  • Title
  • Source.

The source element may be different for each type of academic source you reference, including the publisher's name for books, the journal title, volume, issue and page numbers for journal articles, and the DOI or URL for online sources.

Online tutorial – How to reference

APA is the most common referencing style used at Massey. This 3-part tutorial covers when to include citations, how to write citations using APA Style and how to format an APA reference list.

Author or authors

The author can be a person, people, organisation, group, company, ministry or a combination of people and groups.

In the reference list, the author's surname or family name comes first, followed by the first initials.

Write the author's name exactly as it appears on the source, including hyphenated or 2-part surnames and preferred capitalisation.

Write out organisational authors in full – do not abbreviate them. For example, 'Ministry of Health' not 'MoH'.

1 author

1 author

Put the author’s surname, followed by a comma and the author's initial or initials.

Examples

hooks, b.

van der Spuy, E.

Ministry of Health

2 authors

2 authors

If there are 2 authors, put the first author’s surname, followed by a comma and their initial or initials. Then use an ampersand (&) before the second author’s surname, followed by a comma and the second author's initial or initials.

Examples

Pannell, D., & Rogers, A.

Nikolai, L. A., & Bazley, J. D.

3 to 20 authors

3 to 20 authors

For 3 to 20 authors, separate each author from the others with a comma. There is an ampersand (&) before the final author.

APA uses serial commas. For a list of 3 or more items, use commas between each item – including the 'and' or 'or' before the last item in the list.

Examples

Cunningham, B. M., Nikolai, L. A., & Bazley, J. D.

James, K., Milson, S., Lawton, F., & McBean, S. (2018). Quantitative analysis for beginners. Rata Press.

21+ authors

21+ authors

For works with more than 21 authors, use an ellipsis (…) between the 19th and final author. There should be no more than 20 names.

Example

McDuff, C., Smith, J., Kensington, K., Jones, S., Coughlan, S., Bortolin, L., Witte, M., Scott, A., Newport, A., Jensen, K., Wutzler, J., van Staden, I., McLean, J., Bergsma, G., Dowman, B., Petrie, K., Higgens, D., McCloud, R., Jessop, L., …Duncan, P. (2017). An introduction to quantitative analysis in finance. Houghton.

No author or group author

No author or group author

If no author is named, the source may be written by a group or organisation. This is often true for collaborative or official works from government departments, corporations or other organisations.

In this case, use the group in the author position.

Example

Ministry of Education. (1996). Te Whāriki: Early childhood curriculum. Learning Media.

If there's no group author, the title should be moved to the author position. This method is often used for newspaper and magazine articles and encyclopaedia entries with no identified author. Use the full title.

Example

Beehive updating job wins award. (2007, October 29). Dominion Post, p. A5.

Identical group author and publisher

Sometimes the group author is also the publisher. When you cite a group author, the publisher and author's names are often identical. In these cases, omit the publisher's details to avoid repetition.

Example

Radio New Zealand. (2005). Annual report 2004/2005.

Group authors with bilingual names

Group authors with bilingual names

Some organisations have bilingual names.

The APA Style manual does not provide specific guidelines for bilingual names. However, the general rule for names is to write them as they appear in the original source.

Write names in the order they appear in the original source.

Separate names with a hyphen.

Example

Ministry of Health – Manatū Hauora. (n.d.). Health targets. https://www.health.govt.nz/statistics-research/system-monitoring/health-targets

Same author and date of publication

Same author and date of publication

In some cases, you may need to reference 2 different sources with the same author and the same year.

Order the entries alphabetically, according to the first word of the title, aside from A, An, or The. Then add a lowercase letter, a, b and so on, after the year to distinguish them.

Examples

Johnson, I. (2020a). Publishing

Johnson, I. (2020b). United

Year of publication

The date of publication appears in brackets after the author, with a full stop after the closing bracket. For many sources, including books and journal articles, only the year is required.

Example

Durie, M. (2013). Ngā kāhui pou: Launching Māori futures. Huia Publishers.

Some magazine and newspaper articles also include a month and day or season after the year to clearly identify the source. Include a comma and a space after the year.

For websites, use the most specific date possible in the reference listing – include the month and day, if available. In in-text citations, give the year only.

Examples

Howe, J. (2007, November 16). Manawatu worth $8.1b. Manawatu Standard, p. 1.

Carter, E. (2021, Winter). Specificities of gene markers. Animal Husbandry, 17-34.

Months and dates should always appear after the year.

Note: a last reviewed date implies the web page content has been reviewed and not changed or updated, so use the original date or the last updated date if available.

APA referencing online material: Websites

No date of publication

No date of publication

Dates of publication are found in many places.

  • For books and other print publications, use the copyright date if possible.
  • For web pages, use the most specific date possible – usually the 'last updated' date. If there is no ‘last updated’ date, use the copyright date for the website as the date of publication.

Massey University Library

If there is no year, use n.d., meaning 'no date'.

Author – same author and year of publication

Example

New Zealand Ministry for Culture and Heritage. (n.d.). 100 Māori words every New Zealander should know. http://www.nzhistory.net.nz/culture/tereo-100words

No season, volume or issue number

No season, volume or issue number

If a journal doesn't use seasons, volume or issue numbers, omit the detail from the reference.

Retrieval dates

Retrieval dates

If the source is likely to change, include a retrieval date. For example:

  • dictionary and encyclopaedia entries
  • social media posts
  • maps generated online
  • a website likely to be updated.

The retrieval date lets the reader know the source they retrieve may vary from the version you used. If needed, the retrieval date goes before the URL.

Example

Retrieved July 12, 2025, from https://example.com

Title

Write the main titles of printed material and web pages in italics.

Sometimes, a reference will have 2 titles: the name of an article or entry and the name of the whole work. For example, journals have a name, but each individual article also has a title. Edited books have both a book title and a chapter title. In these cases, write the main title in italics but not the section (article or chapter) title in italics.

APA referencing books: Edited books

Example

Hazledine, T., & Quiggan, J. (2006). Public policy in Australia and New Zealand: The new global context. Australian Journal of Political Science, 41(2), 131–143. https://doi.org/10.1080/10361140600672394

Title format

Title format

Most titles, for example, book titles, only have upper-case letters for the first word of the title, the first word of any subtitle and any proper nouns – the names of places, people or organisations.

Example

Organisational behaviour on the Pacific Rim

Use upper-case letters for all the words in the name of a journal, newspaper or magazine.

Example

Australian Journal of Political Science

Put edition information, report numbers and volume numbers in brackets after the title without an intervening full stop. Don't italicise the information in brackets. If both edition and volume details are available, place both in the same brackets, separated with a comma and the edition details first.

Omit the edition information if it's the first edition.

Example

The Fundamentals of chemistry (3rd ed.).

Developments in robotics (2nd ed., Vol. 2).

Sometimes, you may need square brackets after a title to identify what kind of source it is. Examples include computer software, grey literature such as press releases and audio-visual material.

Referencing other material in APA

Example

Robox script (Version 3.4) [Computer Software].

Source

The source of the work depends on the type of source.

  • Book: use the name of the publisher.
  • Journal article: use the name of the journal, the volume/issue number and the page range of the article.
  • Website or webpage: use the DOI or URL address and not as a hyperlink.

Note: when the author and the publisher are the same, omit the publisher detail to avoid repetition.

If a work isn't locatable by the reader, for example, personal communication or in-house reports, treat it as having no source and don't include it in the reference list.

APA In-text citations: personal communication

Publisher

Publisher

Write the publisher's name or names as shown on the work. Don't include legal terms, for example, Inc. or Ltd.

If there are multiple publishers, then separate the publishers with a semi-colon and list the publishers in the order they appear in the source.

Example

Houghton; Milford Press.

Digital Object Identifier (DOI)

Digital Object Identifier (DOI)

The Digital Object Identifier (DOI) is a unique number allocated to an online publication. A DOI is often used to identify online journal articles, books and other online documents.

If an online document has a DOI, use it instead of the URL address. Start the DOI link with https:// or http://. Don't end the URL with a full stop, as this may affect the functionality of the link.

Example

Gelkopf, M., Ryan, P., Cotton, S., & Berger, R. (2008). The impact of “training the trainers” for helping tsunami-survivor children on Sri Lankan disaster volunteer workers. International Journal of Stress Management, 15(2), 117–135.
https://doi.org/10.1037/1072-5245.15.2.117

Usually, the DOI will appear as part of the source's copyright information or online citation. You can also look up a DOI at http://www.crossref.org/guestquery/

Include a DOI for all works with one, even if you used the print version. If a print work doesn't have a DOI, don't include a URL in the reference. However, include a URL if you accessed the source online.

City of publication

The 7th edition of the APA publication manual doesn't require the place of publication to be given.

The earlier APA 6th edition formats this differently.

Databases with original, proprietary content

Databases with original, proprietary content

Only include database details if it publishes original, proprietary works such as UpToDate or the Cochrane Database of Systemic Reviews. Reference these databases as you would a journal title, title case and in italics after the article title.

List format and order of entries

Format

Use a hanging indent for every entry in an APA reference list. For the hanging indent, every line after the first is moved 1.27 centimetres to the right.

Create a hanging indent in Word

List entries are in alphabetical order according to the first author listed.

Different source types have various formats. There are rules for punctuation, capitalisation and case.

Punctuation is important in the reference list. Look at the examples and use the same punctuation: commas, full stops and brackets. The year of publication, for example, always appears in brackets.

APA Style: elements of reference list entries

APA Style: Basic principles of reference list entries

Order of entries

Alphabetise entries according to the first author's surname or whatever else appears first in the entry. You can use the sort text feature of Microsoft Word to do this quickly and easily.

Microsoft Support: Sort a list

  • If 2 authors have the same surname, alphabetise them according to their first initial.
  • If there are 2 entries with identical authors, order them chronologically, earliest first.
  • If 2 different entries begin with the same author, the entry with only one author comes before entries with multi authors.
  • If 2 different multi-author entries start with the same author, alphabetise by the second author. If the second author is the same, use the third.
