"We need to critically look at Netball New Zealand and the board," Brown said.
"Have we got the right people there? What are our processes?
"It’s really sad that it’s taken so long to get to this point.
"I would’ve hoped that a situation like this could’ve been handled time appropriately in terms of a test series coming up next week."
NNZ removed Taurua, a revered World Cup-winning coach, earlier this week for the upcoming series against South Africa due to unresolved issues.
Widespread reports stated players approached the New Zealand Netball Players Association following a Sydney training camp in January, citing "old school approaches" to Taurua’s leadership.
Former Central Pulse coach Yvette McCausland-Durie has been appointed as interim coach and Southern Steel assistant Liana Leota will assist.
Speculation has been rife online, after NNZ did not reveal the nature of the issues.
Brown, who earned 61 caps for the Silver Ferns, emphasised hard questions needed to be asked of NNZ.
"There needs to be some real good hard questions around how did it get to this point, and why did Netball New Zealand, and the board, let it get to this point.
"There’s so many stories out there.
"Their line is that they can’t discuss it because it’s an employment issue — but it just seems like you’re fuelling the fire in terms of all the speculation.
"I feel it’s getting worse and getting out of control rather than actually being better.
"We have such a rich history, and a meaningful history, that it gets you really down."
A 12-player squad, which could include up to six debutants, is yet to be named for the South Africa series and no captain has been revealed.
"You’ve just got to feel for those players ... because they’ve got a job to do.
"With all these distractions and all this noise outside, that can be really hard."
McCausland-Durie and Leota needed support after being "thrown in the deep end".
"To be fair, I think they probably have a lot of sympathy and acknowledgement for Noels as well, but they need to be there to support," Brown said.
Former netballers and high-performance experts Wai Taumaunu and Tracey Fear, and former All Blacks manager Darren Shand, have been brought in.
Brown hoped Taurua, who has been the national coach since 2018, had been supported.
Brown and Taurua shared the shooting circle at the Capital Shaker and Brown was later coached by Taurua at the Waikato-Bay of Plenty Magic in 2010.
Taurua was "not the most traditional coach", including taking teams on a monk retreat, and was never afraid to challenge players.
"I’m not going to pretend that everything goes right," Brown said.
"I read a comment somewhere that she throws curveballs everywhere and I guess she just pushes you to your limits.
"While I agree with some of the comments around old school, I wouldn’t say she’s old school either.
"I think she’s really innovative, she’s done a lot of research into that.
"As a player, you’ve got to be willing to run the course of the process and I think sometimes as athletes that gets really hard to see the end goal."
The Silver Ferns play their first test against South Africa next Sunday.
