According to sources, Peverley discovered through a series of text exchanges that he was not required this summer.
The 24-year-old, who was the 24th man on the 2010 World Cup soccer roster, has settled in the Bay working for GJ Sports. His partner has also secured employment here since arriving from Wellington.
When Herbert named his World Cup-qualifying squad recently, Napier-based Peverley was listed as a player from Team Wellington, who are playing a warm-up game against Bay United on Saturday, November 2, at a yet-to-be-named venue in Hastings.
It is understood the franchise and Peverley didn't see eye to eye on his contractual worth, believed to be considerably lower than last summer.
The other warm-up games are this Saturday against Auckland City in Taupo and the following Saturday, October 26, against Waikato/Bay of Plenty, also in Taupo.
On the new front, Greatholder has signed exciting players such as England-born David Mulligan, who is recovering from knee surgery after a season with Waitakere United last season, and Sean Morris, a Seattle Sounders under-23 rep, who has been training with the franchise for the past few weeks.
The pair will jostle for positions with another new signing but a familiar face, Bay-born Tom Biss, in the engine room and Harley Rodeka.
Grant Robinson, from San Francisco, is the other American in the matrix.
Treweek understands Morris attended an Auckland City trial but things didn't work out for him so Greatholder lured him to the Bay.
Former Taranaki striker Tomas Mosquera, who played for YoungHeart Manawatu, is among coal-face hopefuls with Sean Lovemore.
"I haven't seen him play but I understand he is exciting and Chris is happy to have him," says Treweek, adding ex-All White and ex-Phoenix Mulligan, 31, is their key signing.
English import centreback Aaron Jones also returns to the fold alongside captain Bill Robertson and so does veteran goalkeeper Richard Gillespie although Bay's Matthew Gould, son of Phoenix assistant coach Jonathan Gould, is a new signing, too, as goalkeeper.
Treweek reckons the team is, from all accounts, further ahead this season than they were in the last one.
Considering the way Bay United finished last season by making the playoffs cut for the first time in the franchise's history, they seem to have a skip in their step this summer.
"It'll take me a little while to get my head around positions and players and everything but I'm looking forward to getting to the game days and some marketing with the players," says Treweek.
Bay United and Central Football, the amateur body of the code, are from now sharing administrative duties.
They will still function under autonomous boards. The structure from CEO will prevail with John McGifford heading Central Football and Bay United.
With more resources, Treweek says, it enables Bay United to drop the shackles of a one-man band operation and save cost in the long term.
The streamlining comes in the belief that it'll provide a transparent pathway to development.
"In terms of growth of football Hawke's Bay United has some input on players coming through the age groups our development officers can identify talent."
In another radical change, Bay United's home games will shift from 2pm kickoffs on Sundays to 5pm on Saturdays.
"Two o'clocks haven't been working greatly in getting numbers to the park ... as we have at the 5pm to 7pm window," says Treweek, 48, who spent eight years with Hawke's Bay Racing including a few under ex-racing boss McGifford, although a decade went into sales and marketing.
