He was a true broadcaster. A journalist, a presenter, a producer. He could do everything and do it well.
He was no one-trick pony. And he was funny and caring towards his co-workers.
And like anyone who strives for high standards Greg could be terribly disappointed if he didn't reach them.
If he had one weakness perhaps it was that he cared too much. He sometimes hid his disappointment in a swagger that some people misread.
It is a terrible day for many in the business and this radio station - and a reminder to always be kind to yourself first.
Meanwhile, in other poignant news, I was very moved by the repatriation yesterday of the remains of 27 New Zealand Army soldiers and one child buried in Malaysia and Singapore. It's called Te Auraki, or the return.
As I commented yesterday afternoon, the pictures on the news will be affecting and they were: 28 coffins, including a tiny white one. Over 160 pallbearers drawn from Defence personnel. The haka, the solemnity and the emotion of the relatives finally reunited.
This morning in the paper, I spied a notice in the Memorial Services column for one of the repatriated. Sergeant Isaac King. Isaac will be celebrated at the Papakura RSA this Friday at 11am.
Now Isaac's daughter went to school with my partner, and his wife was on the telly last night and it gave Helen a bit of a jolt.
She remembers growing up with the King kids and she remembers the big hole that Isaac left behind in the family. His absence hung over the household.
Now, Isaac's daughter has just finished a battle against a health issue and she's been brave and she's done well. So the return of her Dad at this time is an incredible event of closure.
It needed a change of government policy for this to happen and what a good change that was. It is a kind thing to do and in the wake of today's events I think kindness is something we all need to strive for.
