A Jets side who hadn't won in 10 A-League visits to Wellington since 2007 produced fluent attacking soccer to overwhelm the Phoenix 2-1 on Wednesday and climb one spot to fifth.
His side has often struggled for goals this season so it was ironic that van Egmond's men were in sync just a day after key marksman Griffiths announced he was leaving for Chinese Super League Beijing Baxi FC.
The coach reckoned it would have impacted on his players mentally if the match was in Newcastle, but they were nestled in Wellington when the news arrived.
"So it wasn't as bad as if it happened at home," van Egmond said.
"We probably didn't have enough time to think about what had occurred.
"We were pretty composed, kept the ball well and really controlled that game."
Van Egmond had praise for young striker Craig Goodwin, who worked hard up front although the two first-half goals were scored by Adam Taggart and Michael Bridges.
Goodwin looks set to feature in Sunday's match away to Melbourne Victory, with van Egmond keen to rotate his squad for their third game in nine days.
He indicated strikers Bridges and Emile Heskey would be rested while injuries to Zenon Caravella (hamstring) and Sam Gallaway (hyper-extended knee) left them in serious doubt.
Meanwhile, van Egmond welcomed reports linking the Jets with former Australian star midfielder Harry Kewell, who wants to resurrect his career.
"Harry's been a wonderful player and to have someone like Harry come into your football team can only be a positive," he said.
