"Greg was a prominent figure in our newsroom for the last 25 years. He was a wonderful man and a talented broadcaster who strongly believed in the power and importance of journalism in people's lives. Greg was known for his warmth and kindness. It's a very personal loss for us.
"Greg will be missed by us, he will be missed by our colleagues in the wider industry and he'll be missed by our viewers. Our thoughts are with Greg's whānau and friends."
Many people have taken to social media to share their condolences.
Boyed's colleagues have expressed their sadness over the news.
Suddenly my own doubts seem so very trivial. Told this morning of the death of my friend and colleague (and band mate) Greg Boyed. A lovely man, smart, funny, kind, thoughtful. I have no words. Check in on your loved ones.
I’m absolutely lost for words, and so terribly saddened to hear about Greg Boyed. Such a kind, funny and wonderful friend and colleague, who was always there to light up my evenings back when I chipped away on the TVNZ news desk. A wonderful soul taken far too soon.
Greg Boyed.. the man with the witty banter and the perfect piece of advice about just how much is 'too much' for that Auckland property you wanted to buy (he drove a hard bargain, let me tell you). The TVNZ office will never be quite the same. Don't battle your demons alone.
Gutted to hear the news about Greg Boyed... one of the best blokes in the building.. proud to call him a mate.. always had time for a yarn.. I don’t think he ever knew how talented and likeable he was.. we all need to tell ourselves we’re good enough.. and reach out. A tough day
"He was pretty dry, but very funny. He just had the ability to make people laugh. I know of other colleagues of his who have always talked about how relaxed they felt about working with him on the late show."
He said Boyed's sudden death was a huge shock and a "real upset".
McRoberts said Boyed was a skilled journalist who performed at the top of his industry for at least two decades.
"I think to be in the industry as long as he had and to be still performing at that top level you've got to have a real passion for the job.
"He worked on Q&A as well and so clearly had some very good skills there in terms of interviewing and the work that he did. I know when we worked together he was very well respected."
1 News political editor Jessica Mutch she wanted to thank Boyed for all of the "advice, laughs and debates".
TV and radio personality Nathan Rarere said it was a "hell of shock" to read the news about Boyed this morning.
"I shared an office/desk with him and Jody Gill when I first got transferred to Auckland to work at IRN News. He was always so enthusiastic about life and loved a laugh... it was like sharing an office with Jon Hamm."
Rarere described Boyed as "way too handsome and way too nice a person, but was always generous with praise and so, so encouraging in an industry full of selfish people". "He helped me into a taxi after a monster night at John Tulloch's house and made sure I had cab fare to get home. Just the best of the best."
Close friend and former journalist Rachel Grunwell was shocked and devastated by Boyed's death.
"He was an amazing friend. I just wish I could have helped."
She and Boyed ran together "out west" but she said there was often more talking than running.
The pair were both ambassadors at Achilles New Zealand and she said Boyed took huge pleasure in helping other people.
When Boyed helped Grunwell guide a blind runner in the Rotorua Marathon a few years ago, he told her it boosted his confidence.
"He looked bullet proof but he wasn't. He opened up to few people but when he did he had a massive heart. He was just a really kind man and he loved his kids and his family."
She spoke of many special memories - Grunwell plays saxophone and Boyed was learning, she said.
"He was just a really good friend. He gave back so much, to the charity, it actually made him really happy. I've been crying all morning. It's bloody devastating."
Grunwell and another friend had breakfast with Boyed before he flew to Europe a week ago.
Another former colleague of Boyed's said he was a genuinely kind and funny person.
"Not at all the stereotype of a newsreader. He had a really quick wit and a subversive sense of humour. A decent warm person with no big headedness. There's a genuine sadness around TVNZ."
Broadaster Mike Puru has also shared his sadness at hearing the news today.
"Such sad news to hear - Greg was a great man to work and hang with - always striving to be the best he can - always asked what's going on in the TNVZ dressing room ...always had a good laugh and a great respect for others. RIP my friend."
Boyed was to start as contributing to the National Business Review following his return from Europe. Publisher Todd Scott said he was devastated by the news.
Politicians have also shared their condolences.
Prime Minister Jacinda Ardern said she was saddened to hear of Boyed's passing.
So saddened to hear of the passing of Greg Boyed. I’ll be one of many who will have sat opposite him over the years - such a thoughtful interviewer who was quick to share a laugh. My thoughts are with his family, friends and colleagues.
So sorry and shocked to hear the news of Greg Boyed. In all the years I’ve dealt with him, he was always a decent person, without malice and entirely professional. Dreadful to think of his and his family’s pain. #LifeLine
Devastated to hear of the passing of @GregBoyed . Absolutely loved working with him back in the days of IRN News. Will miss you my friend. Moe mai, moe mai, moe mai ra.
Minister of Broadcasting Clare Curran extended her condolences to the family and friends of Boyed.
Terribly sad news today about the sudden death of Greg Boyed at 48. My heartfelt sympathy to Greg’s family and friends and to his TVNZ colleagues. If you need help call or text 1737. If it’s an emergency and you feel like someone else is at risk, call 111.
John Bowden from Achilles New Zealand, where Boyed had been an ambassador guiding disabled athletes for the past three years, said news of Boyd's death was devastating.
"We've had lots of tears and sobbing actually. It's just unbelievable."
Bowden, who also coached Boyed as a marathon runner, was expecting to sit down with Boyed after his return from Europe to work out a running strategy.
"I don't know how I'm going to get over it. That's what hard for us who stay behind... why?"
He described Boyed as being able to easily relate to people with disabilities.
At the Rotorua marathon in May he guided a wheelchair bound athlete on the 10km run. At the start she made it clear she could do the event on her own, Bowden said.
But when the pair came to a steep 800m hill and the athlete asked Boyed for help he told her: "But you said you didn't need any help".
It took an extra hour but the woman completed the course under her own steam.
"That's how Greg was and that's how we work. We've lost a great man in terms of being passionate about athletes with disabilities. He could relate to any person with a disability which was unique about him."
He summed Boyed up as "kind and passionate" and said he was also a very loving family man who had drafted in his older daughter to guide at Archilles New Zealand.
Other have also expressed their saddness at hearding the news.
So sad and shocked to hear the terrible news about Greg Boyed. He was one heck of a nice guy! Thinking of him and his family at this sad time, Godspeed.
Boyed was known for his work on some of television's most recognisable shows - including One News, Fair Go, Q+A, Close Up, Target and Seven Sharp.
