Call Bash Script with Array of Strings with Spaces as Argument

I am fairly new to bash. I want to call a script located on a remote linux machine, passing some normal arguments and one array. The array contains string elements which may have spaces.

I wrote a minimal example:

on the server side: copyFiles.sh

#!/bin/bash

msg=$1  
msg2=$2
shift           
shift
arr=("$@") # Rebuild the array with rest of arguments
for ((i = 0; i < ${#arr[@]}; i++))
do
    echo $msg $msg2 "${arr[$i]}"
done

On the host side:

first="first"
second="second"
array=("arra y1" "array2" "array3")

plink -ssh username@hostname -pw mypwd -batch  " bash scripts/copyFiles.sh $first $second "${array[@]}" "

Output:

first second arra
first second y1
first second array2
first second array3

What I want:

first second arra y1
first second array2
first second array3

Thanks
