B2B Marketing Data FAQ

When choosing what list you need for your direct marketing campaign, you will probably have a number of questions. And of course, we have been asked these many times over the years. So we’ve taken it upon ourselves to start a B2B Marketing Data FAQ.

This FAQ will answer some basic questions you may have about Marketing Data, Direct Marketing & our own data. We’ve gone in-depth and filmed videos for the first questions, and have text answers for the rest below.

If you have any more questions, we’re here to listen and help – reach out at enquiries@whoiswhere.co.nz or call Assia on +64 27 231 8631

It is difficult finding a list of tradesmen because these type of  businesses often operate from a residential premises and do not advertise actively.  

This is a popular list and over the years we’ve gathered a list of 14,000+ tradesmen in New Zealand and over 35,000 in Australia. All split into individual disciplines.

List of tradesmen in NZ and list of tradesmen in Australia are the biggest exception from our rule of having mostly businesses in commercial premises.


whoiswhere originates it’s data from street walking to capture the details of businesses in commercial premises. Because of this we are the only business database supplier who actually has a lot of knowledge about branches as well as head offices and can differentiate between the two.

While branches lack the ability to make major purchasing decisions, franchises often have some leeway. And some branches have more freedom than others, so it pays to know branches too!

When it comes to retail we have all sorts of interesting lists including a list of 467 franchises responsible for over 10,000 locations nationwide. How valuable would that list be for you?


In fact we encourage you to think it through if you actually ever need to speak to branches. And sometimes you do, yet in many cases what is really valuable is the ability to invest in a list with head offices only.

We aim to deliver no data that is older than 121 days. This means we verify businesses up to 3 times a year to ensure accuracy.

We use a 3-step verification process.

Step 1: Gather raw data from the streets. We send teams down NZ streets to gather information about who is where.

Step 2: We research these businesses online to gather as much information as possible.

Step 3: We call these companies to verify that the information we have about them is correct.

We started in 2005 by walking the streets of NZ, noting down who is where – and that’s how we got our name.

So our original dataset comes from a very reliable place! Over the years we’ve continued this and also developed some sophisticated methodologies to ensure accuracy.

One good thing about being a relative newcomer in a stale industry is being able to introduce superior ways of doing things for the benefit of our customers.

Yes, with some clauses.

We will refund or exchange any records over a 10% inaccuracy rate.
The nature of our business means although we try to keep data as accurate and up to date as possible, people continue moving! We feel a 10% inaccuracy rate is reasonable and will ask for verification of this through returned mail or call records showing that the data is incorrect.

Certainly – reach out today and we’ll organise a fresh sample of our data straight away.
