Be positive, be patient, be polite, be a good sport 

• Before commencing a game, introduce yourself to anyone you don't know and offer a good match to each player on the court. 
• Return the "let" ball immediately (under the net) to the server. All balls should be returned this way. 
• Do not return the first fault ball. 
• It is courteous and advisable to remove any fault ball still on the court before the second serve. 
• The result of the serves played is the call of the receiver (in the absence of an umpire) and must be played unless immediately called out. 
• In or out calls are first and foremost made by the team or a player on the side where the ball lands. 
• On the line, just touching the outside the line, or any doubt whether the ball is close to or touching the line is counted as "in" (benefit of the doubt). 
• If a call is seriously in dispute, please offer to replay the point with a new serve. 
• The server calls out the score immediately before the next serve. 
• Disagree with the score? Politely tell the server. 
• Any intrusion from off the game court which disrupts/interferes with the safety of the players and/or play must be called a "let" ASAP and not after the point has ended. 
• Should a let be called due to an unexpected intrusion from off the court, then it is a replay of two serves. 
• The tennis net is out of bounds [anyone who touches the net in play, forfeits the point]. 
• Do not move under or over the nets. 
• Do not interrupt other games/players by walking around or onto their game/court. Where possible, walk around the outside of the court's fences. 
• Every absentee from an up & coming team game must find a replacement and advise the captain or a team member of the replacement's name and contact info. 
• Please be on time for your game - everyone's time is valuable. 
• Running late? Please advise your captain. 
• Social games do not mean that a player from the opposite team is allowed to always target the the weakest player. 
• At the end of the match, shake hands with all the players. 
• Changes of "ends" for tournament play: after 1st game, 3rd game, and odd numbers. 
• Tie breakers - 6 games each, start with 1 serve from the right; change service for 2 serves, 1st from the left then the right, change of ends at 6 points, 12 & so on first to seven points or win by two points. 

Mangawhai tennis should be fun, fair and friendly.
