The Tonga Amateur Sports Association, TASANOC, has sacked its long serving chief executive officer Takitoa Taumoepeau, and office manager 'Ahosivi Kaitapu.
The executive committee stated that the decision was a result of internal restructuring of administrative staff.
Following the announcement on Tuesday, the TASANOC offices were then closed to the public with a notice it would reopen next Wednesday.
However Matangi Tonga online says Takitoa Taumoepeau will still remain as the Secretary General in the organization, a voluntary position that is elected every four years.
A new TASANOC executive committee was elected in January of this year, at the time that concerns were raised about the economics of running the national body.
At the last annual general meeting, the financial accounts for 2012 showed that the administration expenses had exceeded budgeted income by over 137 thousand US dollars.
The main expenses were the salaries and wages of the CEO and five staff, the CEO's housing and travel allowances, general overseas travel and vehicle expenses.
At the same time the budgets for sports development in Tonga were under-expended.
TASANOC is supported through various programmes of the International Olympics Committee, and Tonga's national sports federations.
