What is the NZDF Aptitude Test?

SHL has developed the NZDF Aptitude Test to evaluate New Zealand Defence Forces Candidates' cognitive abilities. NZDF Aptitude Test is an integral part of the NZDF application process, and you may be required to take it for most positions available at the NZDF - whether a pilot or an accountant. 

The test consists of 2 subtests- SHL General Ability and SHL Mechanical Comprehension Test. Like other army aptitude tests, these tests cover a wide range of subjects, including inductive reasoning, numerical reasoning, mechanical reasoning, and deductive reasoning.

SHL General Ability Test

The General Ability Test consists of 30 questions to complete within 36 minutes

  • Numerical - This particular set of questions highlights the need to deal with interactive, complex data that is presented in tables and graphs. This part of the assessment focuses on your ability to extract, calculate, and come to conclusions based on numerical data. On each question, you'll be presented with numerical data arranged in a graph, table, etc. You'll be asked different questions and will need to be able to draw conclusions and perform numerical calculations based on the data.  
  • Inductive - SHL Inductive questions revolve around finding the logical rules represented in shapes’ colour, position, etc. The purpose of an inductive reasoning test is to evaluate the way you think and react to new rules and situations. The questions often require you to identify patterns of rules in diagrams.
  • Deductive - The SHL Deductive questions examine your ability to draw logical conclusions out of given information. This will usually be measured by scheduling tasks or ranking items based on constraints. The important thing about these questions is that there is always a logically correct answer.

SHL Mechanical Comprehension Test

The SHL Mechanical Comprehension Test assess your ability to understand mechanical concepts. In each question, you'll be shown images of simple machines, tools, or objects, and you'll be asked to predict the outcomes or to describe how the objects shown would interact.

The SHL Mechanical Test consists of 18 questions to complete within 15 minutes. 

NZDF Aptitude Practice Test

It is well known that proper practice and familiarity with the test questions can significantly reduce stress and anxiety on test day and raise your chance for success. That's precisely why our experts at JobTestPrep have made a dedicated short free sample test for you.

The sample questions below don't include all the different types you may face in the test, but most of them. If you want to practice more types of questions, you can check out our PrepPack.

Numerical Reasoning Questions

Note: since all numbers are given in hundred thousand ('000), the three zeroes can be ignored in the calculations.

To calculate the change in the company's revenues, in percentage, use the following formula:

% Change = ((New Value – Old Value) / Old Value) * 100

Where the Old Value is the company's revenue in 2012 ($123,000) across all calculations (since the rise in revenue is measured in comparison to this year's revenue specifically).

The New Value is the company's revenue in the year compared with 2012. This value is changing between years.


In 2013 the % raise is:

((130.38 – 123) / 123) * 100 = 6%

In 2014 the % raise is:

((157.44 – 123) / 123) * 100 = 28%

In 2015 the % raise is:

((193.11 – 123) / 123) * 100 = 57%

In 2016 the % raise is:

((178.35 – 123) / 123) * 100 = 45%

In 2017 the % raise is:

((189.42 – 123) / 123) * 100 = 54%

In 2018 the % raise is:

((199.26 – 123) / 123) * 100 = 62%


Inductive Reasoning Questions

Which Image should be the next in the series?

Click Here To See The Answer

In this series, there are 3 small shapes with different patterns of movement: Green, light pink, and yellow triangles.  

In each step, the green triangle moves 2 steps in a clockwise direction. 

The light pink triangle moves 2 steps in a counterclockwise direction. 

Recognizing these two patterns will already lead you to the correct answer. The yellow triangle doesn't show a clear and repeated movement pattern, making it hard to identify the pattern that it follows. However, its' pattern is not necessary in order to find the solution.

Deductive Reasoning Questions

Three travellers - John, Kate, and Lenny - came back from three trips to the following countries: Mauritania, Nepal, Oman, Peru and Qatar. The countries each of them visited must be consistent with the following rules and conditions:

  • Each country was travelled by at least one of the travellers.
  • Each traveller took only one trip during which he or she travelled to only two or three different countries.
  • Only one traveller travelled to Qatar.
  • Every traveller who travelled to Mauritania also travelled to Nepal.
  • A traveller who travelled to Qatar did not travel to Peru.
  • John travelled to all the countries Kate travelled to.

If Lenny did not travel to Qatar, which statement cannot be true?

A. Lenny travelled to Peru.
 B. Lenny travelled to Oman.
 C. John travelled to Mauritania.
 D. Kate travelled to Mauritania.
 E. Kate travelled to three different countries.
Correct Answer
Incorrect Answer

The correct answer to this question is the only response that is not possible. This means that the four wrong answer choices are at least possible, if not necessarily true.

If Lenny did not travel to Qatar, and according to the derivatives Kate cannot travel to Qatar, then the traveler who must have traveled to Qatar is John. Since a traveler who traveled to Qatar cannot travel to Peru (q → ~p), John did not travel to Peru, and therefore Kate also did not travel to Peru (~J → ~K). Therefore, the traveler who must have traveled to Peru is Lenny.

The general setup for this question is:
















The following setup shows that responses (a) through (d) are possible, and are therefore not the correct answers: 





















Note: after eliminating answers (a) through (d), checking answer (e) is redundant – it must be the correct answer.Answer (e)- If Kate travelled to three countries, then John must have travelled to the same countries as Kate (K → J). In addition to the countries Kate visited, Qatar has also been travelled by John. This means that John visited 4 countries, in contradiction to the rules ('each traveller visited 2 or 3 countries'). Therefore, the information in the response cannot be true.

So, "Kate travelled to three different countries" cannot be true- which is why E is the correct answer.

Mechanical Reasoning Questions

How will each of the horses behave when pushed forward?

SHL Mechanical Comprehension Test Answers
A. Both horses will move forward
B. Both horses will move forward, but Horse B will also move up and down.
C. Horse A will move forward, Horse B will move up and down.
D. Both Horses will move forward and up and down.
Correct Answer
Incorrect Answer

While the four large wheels on the base will move both horses forward, Horse B will also move up and down.

Here's why:

The front axis of horse B is not straight (as opposed to horse A) and has an arm in the perpendicular direction. Therefore, it will convert some of the wheel rotation to an up-and-down movement, as depicted in the following diagram (side view):

SHL Mechanical Comprehension Test Answers

The arm rotates "inwards," pushing the horse leg up as it goes up (black) and down as it goes down (dashed grey).

Can I Retake The NZDF Aptitude Test?

Yes. NZDF allows a maximum of 2 attempts of the test. You can take the test again after 6 months. If you fail them both, you won't be able to join the NZDF.

What Other Stages Are In The NZDF Application Proccess?

First, You'll need to gather all the relevant documents and make an online application and registration. 

Second, You'll need to pass the NZDF Aptitude Test and complete the NZDF Fitness Test. 

Third, You'll need to attend and pass an interview. 

After the interview, you'll receive a job offer. If you sign and agree to the terms of employment, you'll continue to a Full Medical Check, which will be the last stage of your process. 

How Long Does the Application Process Take?

The time between submitting your application and the first day of training typically takes 3 – 18 months
