Central Football has just published their list of fees for 2019
They have a system where you pay by player for Central Football membership (graduated from $9 per player at first kicks level to $32 per player as a senior). Then there is a CF football league entry which is per team ( $60 for Fun Football - 7th and 8th grade to $820 per team for Senior Men and women - Prem and Div 1) Add on ground fees (to be advised) and then NZF Affiliation fee ( $34.44 for first kicks to $643.36 seniors - per team).
By my reckoning, that would mean our Prem team (based on 2018 with 18 players) would pay to Central Football a total of $576 (CF membership), plus $820 (League entry) plus $643.36 NZF. A total of $2039.36 + GST and with ground fees still to come.
