For more information about the Olympas, go to 'Do I need an Olympos sportscard?'

Registration fee. When you want to become a member, you will have to pay a one-time registrationfee equal to the costs of the KNZB-contribution and the costs for a potential license for swimming matches.

Competition fee. For members who play in a waterpoloteam there's an additional competition fee of about €70,00. This fee is collected at the second contribution collection.

Competition license swimming. For external swimming competitions (except for NSZK's and the NKS) a license is required. A license can be acquired through Zinkstuk for €35,05. Read more about the license at ''When do I need a startlicense and how does it work?'


You can also join at the middle of the year as member, then it could be possible that you pay only half of the training fee. For more information about this please send an e-mail to secretaris@hetzinkstuk.nl

You are obliged to have a valid Olympos sportscard registered to Het Zinkstuk during your entire membership. This does not apply for contributors.

The Olympos sportscard has to be bought via the sportcenter Olympos and then has to be registered to Het Zinkstuk. Don't know which kind of sportscard to buy? Do the check via this tool.

Arrange your Olympas via this link or the Zinkstuk-registering via this link. Your Olympas must always be at least valid until the next unsubscribe-date (valid until 31-07-XX or 31-01-XX).

When the registration of your sports card expires you will receive a message that tells you you have to extend you registration. As long as you don't have a valid and to Het Zinkstuk registered sportscard, you cannot take part in the practices and activities. If you remain in jeopardy you will receive a fine of 110% the amount Het Zinkstuk would otherwise receive for you from grants. The dates on which the board checks your sportscard are the first of November and April.

You will need a license when:

  • You are part of a waterpoloteam and play in the competition, or
  • You want to participate in KNZB-matches in addition to the NSZKs.

You can request or stop a license yourself via your profile on the website. A start licence is valid from Januari 1st till December 31st and will be automatically extended if you don't cancel it before January 1st via your profile on the website.

Contributors cannot subscribe for a start license.

The contribution is collected at the end of January and the end of July. For contributors the contribution is collected at the end of July.

Other costs, for example those for activities, are collected at the end of each month.

Costs are collected via the payment method you selected at your registration.

Two weeks before a cost collection you will receive a message containing the amount that will be collected.

In case you choose to transfer the costs yourself or when the automatic collection did not succeed, you are required to make the payment within two weeks. Contact information can be found on this page.

A maximum of three payment reminders will be sent every two weeks. The board reserves the right to suspend persons who do not fulfill their payment obligation.

The unsubscribe-dates are the outer moments to end or change your membership. These are as follows:

  • For members: January 1st and July 1st
  • For contributors: August 1st

End your membership or convert it before one of these dates via this link.

As a member you are entitled to suspend your membership for half a season. You can do this once a season by sending an e-mail to secretaris@hetzinkstuk.nl. In case the board honors your request you will only have to pay half the contribution. During the suspension of your membership you cannot prescribe to any of your rights as a member.

Please note that in the event of a violation you might still have to pay the entire contribution and any missed grants under penalty of suspension.

When you are no longer a student you are allowed to remain a member for one season at the regular contribution cost plus 28 euros. After that season you can apply for dispensation by sending an e-mail to secretaris@hetzinkstuk.nl. If you do not do this, you will be unsubscribed automatically.

When dispensation is assigned, the default contribution becomes:

  • 1st year dispensation: €157,70
  • 2nd year dispensation: €315,00
  • After 2nd year dispensation: obligated unsubscribing

It is possible to become a contributor when your membership ends. As a contributor you can still participate in the activities and you support the association. You can stop your membership or convert it to becoming a contributor via this page.

You can unsubscribe via this page.

For members applies: after an unsubscribe-date follows a notice period of 1 month in which your membership continues. During the notice period it is not possible to participate in matches organized by the KNZB. If you want to keep participating in these matches you have to send an e-mail before the unsubscribe-date to secretaris@hetzinkstuk.nl.
