"It is pretty full-on for sure but I just love it, especially helping with the younger age groups," said Lacy.
"At the Oceans for four days we were on the beach at 7am and were getting off at 6pm.
"My wife Megan does the admin stuff and is on the board here at Mount Maunganui, my younger daughter Georgia has just turned 12 and she does the running of results and food around, and gets the medals ready for presentation. My eldest girl Jess will be competing this weekend but last week she helped coach the under-14s."
One recent change Lacy likes is a greater emphasis on safety after the tragic drowning of a young surf lifesaver in Australia last summer.
All competitors must now wear brightly coloured vests.
"It is a step forward and we are getting more and more health and safety conscious on the beach. On the start line before going in the water, we are always counting competitors out and counting them in."
The National Surf Lifesaving Championships continue all day today from 8am and will conclude on Sunday afternoon.
