"The relationships Rotorua Lakes Council has work very, very well.
"This is a way of looking at increasing and improving on those relationships."
Hutt City Mayor Ray Wallace will chair the conference.
"It will be very interesting for me to go and to be able to report back to my fellow councillors who view the sister city relationships as less important."
Gould will report back to council on June 28 at the monthly council meeting.
In yesterday's council meeting, councillor Trevor Maxwell said he was "more than happy" for Gould to attend the conference.
"He is a worthy choice."
Councillor Merepeka Raukawa-Tait said the conference was about how the council could work smarter.
"It's about becoming more informed.
"A big thank you to Maxwell and Gould who are the ones that are always on the front line and fostering these relationships."
Sending Gould to the conference will cost Rotorua Lakes Council $1448.
